Research Methodology

Marguerite Gaulin (1627–1703)

A companion to the documentary biography — how the story was assembled, source by source, against BCG standards.
Storyline Genealogy

Why This Page Exists

Genealogy is documentary research before it is story-telling. The story is the form in which the research is presented — not its substance. The two pages serve different purposes: the biography is the narrative; this page is the machinery.

The documentary biography of Marguerite Gaulin tells her life across seventy-five years and two continents. This methodology page documents how that biography was assembled: which sources were used at which evidentiary weight, how source conflicts were resolved against the primary record, what techniques were applied when no record survived, and which questions remain genuinely open and why.

It also names what was not done. Conclusions are sourced to primary records wherever those records survive; secondary references are flagged as such; discrepancies are documented before they are resolved; and language is calibrated, throughout, to distinguish documented fact from probable inference. Where a question cannot yet be answered from the available record, the biography says so, this page says how to try, and neither invents the missing detail.

It also keeps its own errors visible. Two conclusions previously published on this page have since been withdrawn against later evidence, and both are retained below with the reasoning that produced them and the record that retired them. A methodology page on which nothing has ever failed is not a methodology page.

This is the standard of the Board for Certification of Genealogists (BCG) — the Genealogical Proof Standard, the Reasonably Exhaustive Search requirement, and the discipline of citing every claim to a verifiable source. For a portfolio-grade documentary biography, the rigor matters. This page is where the rigor is visible.

The Research Arc

The Marguerite Gaulin project unfolded across nine successive research sessions, each adding a layer of documentation to what the previous session had established. The arc moved geographically as well as evidentiarily — from compiled secondary references through Quebec primary records, back across the Atlantic to the original French parish registers, forward again into the Beauport baptism network, and finally into a systematic audit of every register act against the database card that indexes it.

Batch 1
Baseline. Gagné's Before the King's Daughters, Lebel and Laforest's Our French-Canadian Ancestors, and the database compilations (PRDH, GFNA, Fichier Origine) were consulted to establish the framework: birth, marriage, ten children, death. The research log opened with secondary-source baseline entries, and the first discrepancies surfaced — baptism year, burial month, Marie Crête's marriage count.
Batch 2
Quebec primary records. Twenty register images entered the log: the 1654 Crête-Gaulin marriage at Sieur Giffard's house, the 1659 baptism of Marguerite I at the same manor, the 1666 census enumeration, the 1670 marriage of Marie to Robert Pepin, the 1703 burial of Marguerite, and the 1717 burial of Jean. Several discrepancies resolved immediately against the primary record.
Batch 3
The Louis arc. Primary records for Louis Crête's 1685 marriage in France and burial at Saint-Laurent (Île d'Orléans), together with the burial register of the infant Marguerite II in 1663. The Louis-at-sea narrative shifted from contested (was he a bachelor?) to documented (he had married in France three months before his death).
Batch 4
The Perche origins. French parish records from Saint-Aubin de Tourouvre and Saint-Martin-du-Vieux-Bellême (AD-61) added Jean Crête's 1626 baptism, Antoine Crête's 1592 baptism, the 1619 marriage of Antoine to Jeanne Legrand, and Marie Crête's 1632 baptism (Jean's sister). The Badeau land purchase of 1654 and the descent line through Marie's second marriage to Jean Brideau were added.
Batch 5
Perche context plus two more censuses. The Janssonius 1640 map of Perche, the Saint-Martin parish church photograph, and the surrounding landscape. The 1667 and 1681 royal censuses entered the log alongside the 1666 baseline — three enumerations of the same household across fifteen years, documenting the economic ascent from fifteen arpents under cultivation to forty, from six cattle to thirteen.
Batch 6
The baptism windfall. Primary register images for all ten Crête children's baptisms entered the log. Seven were visually transcribed; three were added by CDN URL pending transcription. The full priest-and-godparent network across fifteen years became visible. The Crête-Giffard-Juchereau relationship reframed from patron-client to quasi-familial.
Batch 7
The notarial expansion. The 1693 Crête × Marcou marriage contract entered the log as D-057 — a three-page primary act before Notary Paul Vachon (certified copy by Duprac) documenting Marguerite's illiteracy directly: she was named among those who "declared not to know how to write or sign." The act also documents the intergenerational transfer of six arpents of the Buisson fief to son Pierre at his marriage. Alongside it, eight notarial citations from the Parchemin database (Vachon, Becquet, and Duprac greffes, 1658–1707) entered the log as D-058 through D-065. The most consequential among them — the Vachon act of 4 August 1666 (D-059) — names Claude Guion and Catherine Collin of Île d'Orléans as the actual vendors of the Dubuisson fief parcel, correcting a longstanding secondary-source attribution to Joseph Giffard. Five new discrepancies were tracked; four resolved against the primary record.
Batch 8
The Buisson fief documentary chain complete. Five new primary sources entered the log, closing the foundational research lead from earlier batches. The 1655 dénombrement of the bourg du Fargy (D-066) emerged as the earliest known Jean Crête land record in Quebec, documenting a thirty-eight-year Crête-Marcou neighbor relationship before the 1693 children's marriage. The 11 August 1666 act of foi et hommage to Robert Giffard (D-067), one week after the Vachon sale, preserved the medieval seigneurial ceremony in full: kneeling at the castle gate, bare-headed, calling out three times to Monseigneur. The 25 April 1673 aveu et dénombrement to Joseph Giffard (D-069) established the full Buisson fief provenance chain back to its origin on 14 March 1634 at Mortagne, Perche, before Notary Mathurin Roussel — a direct Perche-to-New-France documentary thread spanning 39 years from grant to avowal. A surveyor's record (D-068, 5 November 1673) physically marked the parcels. A 1712 receipt from Nicolas Dupont (D-070) — the same Dupont who was Jean Crête's adjacent seigneur in 1673 and the Pepin arbitrator in 1705 — documented Pierre Crête's continuing joint partnership with his brother-in-law Jean Baptiste Lefebvre nineteen years after the original 1693 purchase. One discrepancy (DC-19, a catalog-date typo) was resolved against the body of the primary record.
Batch 9
The database audit. Undertaken while preparing the visual archive, this pass compared every parish register act in the corpus against the database card that indexes it, one by one. It was the least glamorous session of the project and the most corrective. Three outcomes: the Soudain/Jourdain working identification resolved to Jourdain on the strength of the husband's own autographs (DC-16); the death date of the daughter Marie Françoise was found to be twenty years wrong and corrected to 29 November 1702 against the register of the Hôtel-Dieu (DC-20); and a burial-date conflict for Louis Crête was opened (DC-21). The Marie Françoise correction in turn reopened DC-17, since a daughter who predeceased her mother by seven weeks cannot hold a quarter share in her succession. A source list attributed to a 1654 notarial contract was also withdrawn as geographically impossible. The session is a demonstration of why derivative sources are audited rather than trusted: the errors it caught had been sitting inside published conclusions.

By the end of Batch 9, the documentary footprint stood at seventy catalogued documents, forty-seven of them primary-source. Twenty-one discrepancies are tracked: sixteen resolved, five open. The Buisson fief documentary chain stands image-verified end to end, save the 96-livre receipt of 1 June 1667 referenced in earlier research notes.

The Source Hierarchy

Genealogical claims are not all worth the same. A parish register entry made by the curé who witnessed the baptism in 1657 is not the same kind of evidence as a 2010 user-submitted entry on a public family tree, even when both name the same date. The Genealogical Proof Standard requires that conclusions rest on the strongest available evidence, with weaker evidence flagged for what it is. This project applied four tiers.

Tier One

Primary Sources

Records produced contemporaneously by people whose institutional role required them to record what they witnessed. These carry the highest evidentiary weight.

  • Parish register entries (baptism, marriage, burial) — original ink on the register page
  • Notarial acts (marriage contracts, inventories, sales, quittances)
  • Institutional registers (the Hôtel-Dieu du Précieux-Sang patient rolls)
  • Royal censuses (Nouvelle-France 1666, 1667, 1681)
  • Sovereign Council judgments
Tier Two

Derivative Primary Sources

Curated transcriptions and indexes of primary sources, produced by scholars or institutions with documented methodologies. Reliable as pointers but not the document itself — when the original register is accessible, we return to the register. Crucially, a card and the act it indexes are one witness, not two: their agreement is not corroboration.

  • PRDH-IGD (Programme de recherche en démographie historique)
  • Fichier Origine
  • Genealogy of French in North America (Beauregard)
  • Godbout's Origine des familles canadiennes-françaises (1925) — a special case: verbatim parish-register transcriptions compiled before twentieth-century access restrictions, treated as primary when no register photograph is available
Tier Three

Published Secondary Sources

Compiled biographies and historical works that synthesize primary research. Useful for framing questions and corroborating primary findings, but not themselves evidence. Where they conflict with the primary record, the primary record governs.

  • Gagné, Before the King's Daughters: The Filles à Marier, 1634–1662 (2002)
  • Lebel & Laforest, Our French-Canadian Ancestors, vol. 3
  • Specialized monographs on Beauport, Perche emigration, and seigneurial history
Tier Four

Not Used as Evidence

Crowd-sourced public family trees and unsourced online compilations are useful only for identifying potential records to verify. They have no independent evidentiary value and are not cited in this biography. Their characteristic failure is that an error, once entered, carries no trace of its origin and no means of retraction — which is precisely what makes them unusable as evidence and hazardous as a source of leads.

  • Unsourced blog posts and forum discussions

Defensible Language

Words are not neutral in genealogical writing. The phrase "Marguerite was born in 1627" makes a different claim than "Marguerite was probably born in 1627" or "Marguerite's baptism record places her birth in May 1627." Each carries a different evidentiary weight, and a careful reader should be able to tell, from the language alone, what kind of evidence stands behind any given sentence.

The biography uses the following calibration:

Phrase Evidentiary basis
"baptized," "married," "buried" Primary register record cited; date and place specified
"the record shows" Primary record exists and is transcribed in the research log
"per [Source]" Secondary or database source named where primary is unavailable
"highly probable" Strong indirect evidence; multiple independent secondary sources align; no primary conflict
"likely" / "appears to" Preponderance of evidence; some uncertainty remains
"inferred from" Explicit inference from indirect evidence; the inferential step is named
"open question" Discrepancy unresolved; no clear primary record found
"withdrawn" A claim previously published here, retired against later evidence; the earlier reading and the record that retired it both stay visible

The discipline matters most at the seams — the moments where the documentary record runs thin and inference begins. The crossing of the Atlantic in 1654 is one such moment: no passenger list, no contract, no register entry places Marguerite on any specific ship. The biography says so in those words. It does not invent a name or a port.

Resolving Source Discrepancies

Across the published references, the database compilations, and the primary records, twenty-one substantive discrepancies surfaced during the research. Sixteen resolved against the primary record. Five remain open and are flagged as such in the biography.

The resolution method, in every case, was the same: locate the primary source closest to the event in question, transcribe it carefully, and let it govern. Where two primary sources disagreed (rare, but it happened — the 1666 census misrecorded "François Creste" where the 1660 baptism register named Françoise), the source closer in time to the event being recorded took precedence.

Two entries below are marked withdrawn or reopened. Both were published on this page as resolved and both were retired by evidence that arrived later. They are kept in place, with their original reasoning intact, because a discrepancy register that silently deletes its errors is not an audit trail.

The Twenty-One Discrepancies

Each discrepancy is named, the sources in conflict are identified, the resolution method is documented, and the status is marked. Withdrawn readings stay visible with the evidence that retired them. The full text of each is preserved in the working research log (sheet "Discrepancies," entries DC-01 through DC-21).

Resolved

DC-01: Marguerite's Baptism Year

Lebel/Laforest (1979): baptized ca. 1625
Godbout (1925), AD-61: baptized 14 May 1627
Resolution: Primary register transcribed verbatim by Godbout in 1925 (before access restrictions). The entry reads "Le quatorzième de may aud[it] an (1627)." Confirmed by Fichier Origine #241711, which also supplies an image of the act itself.
Resolved

DC-02: Marguerite's Burial Month

Lebel/Laforest: buried February 1703
Beauport register (primary): buried 15 January 1703
Resolution: Burial register of Beauport, 1700–1759 copies, Drouin Collection. The entry is unambiguous: 15 January 1703. Confirmed against the 17 April 1703 marital community inventory which references her death some weeks prior.
Resolved

DC-03: Mother's Surname — Boulemer vs. Bonnemer

Most secondary sources: Marie Bonnemer
Saint-Martin parish register (Godbout): Marie Boulemer
Resolution: Both forms refer to the same woman. The primary register uses "Boulemer," which Godbout's index expressly cross-references with the more conventional "Bonnemer." The biography uses Boulemer in primary citations and Bonnemer in narrative reference, with the variance noted.
Resolved

DC-04: Antoine Crête × Jeanne Legrand Marriage

PRDH Couple #72: married 1620
Saint-Aubin de Tourouvre register (AD-61): married 29 October 1619
Resolution: Primary register at Saint-Aubin de Tourouvre, witnessed by Father Guillaume Loyseau. The register entry is dated 29 October 1619 with no ambiguity. PRDH's "1620" appears to be a database transcription error.
Resolved

DC-05: Identity of Infant Marguerite Buried 1663

Earlier secondary sources: the elder Marguerite (b. 1659) died as infant; the younger (b. 1663) survived to marry Pierre Gaillou.
1666 census + primary burial register: the younger Marguerite II (six weeks old) was buried in May 1663; the elder Marguerite I survived and married Pierre Gaillou in 1678.
Resolution: The 1666 census lists "Marguerite Cresté, 7" alive in the household three years after the 1663 infant burial. The burial register names "petite fille agée d'un mois et demy, fille de Jean Creste, habitant de Beauport" — aged one and a half months, which fits the March 1663 birth of Marguerite II precisely. The identification is secure; the exact day of the burial is a separate and minor open reading, carried under DC-21.
Resolved

DC-06: Louis Crête's Marital Status

Lebel/Laforest: Louis died a bachelor in 1685
PRDH Couple #5533 and the secondary literature: Louis married Madeleine Briault on 28 May 1685, three months before his death
Resolution: The marriage is recorded in PRDH Couple #5533, which places it in France on 28 May 1685; the secondary literature localizes it to Saint-Sauveur de La Rochelle. No register image has been retrieved for the French act, and the Saint-Sauveur attribution accordingly awaits confirmation from the La Rochelle register itself. The fact of the marriage is nonetheless secure: Louis's burial three months later, "on the boat of Sieur Niel on the day of his return from France," is consistent with a marriage during the France voyage, and Madeleine Briault's remarriage at Notre-Dame de Québec on 14 May 1686 names her as his widow.
Resolved

DC-07: Louis Crête's Age at Death

Some secondary sources: age 28 at death
Saint-Laurent burial register + 1656 baptism: age 29 at death
Resolution: Louis was born 6 May 1656 per the primary baptism register at Notre-Dame de Québec, and buried in August 1685 at Saint-Laurent (Île d'Orléans). His age was twenty-nine years and three months at death, consistent with the register's own "agé d'environ trente ans." The exact day of burial is carried as open under DC-21.
Resolved

DC-08: Jean Crête's Age at Death

Several secondary sources: died at age 89
Beauport burial register: "environ 93"
Tourouvre baptism (1626) + Beauport burial (1717): died at age 90
Resolution: Jean was baptized 23 November 1626 per the primary register at Saint-Aubin de Tourouvre, and buried 5 March 1717 at Beauport. His age was ninety years and three months at death. The priest's estimate of about ninety-three is a rounding by a clerk who had no access to a Perche register; the computed figure governs, and both are stated in the biography.
Resolved

DC-09: Diocese Designation at Jean Crête's Baptism

Some derivative sources: diocese of Chartres
1626 primary register, Saint-Aubin de Tourouvre: diocese of Chartres confirmed
Resolution: The Tourouvre parish belonged to the diocese of Chartres before the French Revolution, despite its location in the modern department of Orne. Confirmed against the parish register header and Fichier Origine #241071. No actual conflict — an apparent discrepancy that resolved as terminology clarification.
Resolved

DC-10: 1666 Census — "François Creste, 5"

1666 census: "François Creste, 5, fils" in the Jean Crête household
All other sources, including the 1660 baptism register and 1667 census: the 1660-born child was female — Marie Françoise
Resolution: The 1660 primary baptism register names "Françoise Creste" unambiguously female, baptized 1 August 1660 with Joseph Giffard as godfather and Françoise Juchereau as godmother. The 1667 census, taken one year after the 1666 enumeration, lists her correctly as "Françoise, 7." No son named François appears in any Crête record before or after 1666. The 1666 census-taker mis-recorded the name and sex.
Open

DC-11: Marguerite's Exact Year of Atlantic Crossing

Gagné: arrived ca. 1652–1654
Fichier Origine: arrived ca. 1652–1654
Primary records: she was present in Beauport for her 13 September 1654 marriage
Status: The voyage must have occurred earlier in 1654 or in 1652–1653. No passenger list, contract of engagement, or ship's manifest has been located that names her specifically.
Open

DC-12: Existence of Pierre Gaulin's Baptism

Godbout 1925: Vincent Gaulin and Marie Boulemer had four children whose baptisms appear in the Saint-Martin register: Vincent (1620), Marie (1623), Marguerite (1627), François (1630).
PRDH Couple #125 and other references: a fifth child, Pierre, born 14 May 1627, who emigrated and died 1677 at Ste-Famille
Status: No baptism for a Pierre Gaulin appears in Godbout's transcription, though his adult Quebec life is well documented. Whether the omission is Godbout's, the register's, or the result of a lost page remains undetermined.
Open

DC-13: Pierre Gaulin's Twin Status with Marguerite

Gagné and PRDH Couple #125: Pierre and Marguerite Gaulin were twins, both dated 14 May 1627
Primary record: Marguerite's 1627 baptism stands alone in Godbout's transcription
Status: If Pierre existed, his twin status cannot be confirmed from any primary record currently in hand. A baptism on the same date as Marguerite's would resolve this; absence of any record cannot. The question remains open pending DC-12.
Resolved

DC-14: Buisson Fief Vendor — Giffard vs. Guion/Collin

Secondary sources / working narrative: Joseph Giffard sold the Dubuisson fief to Jean Crête in August 1666
Primary Vachon Vol. II p. 21 (D-059): the sellers were Claude Guion and Catherine Collin, his wife, of Île d'Orléans
Resolution: The primary notarial record names Guion and Collin as the vendors of a parcel within the Dubuisson fief in the seigneurie of Beauport. The Giffard family was the over-seigneur of Beauport — within whose seigneurie the fief sat — but did not sell directly to Jean Crête. The subsequent aveu et dénombrement rendered to the Giffard line was for suzerainty, not vendor relationship. The Crête-Giffard relationship remains documentarily rich in its sacramental dimensions; the 1666 land transaction was a private sale within the seigneurie. Biography corrected accordingly (five edits across Sections 7 and 11).
Resolved

DC-15: Marguerite Crête I's Husband — Gaillou vs. Gaultin

PRDH and most secondary sources: Pierre GAILLOU
1706 Chambalon Quittance (D-040): "Pierre Gaultin"
Resolution: Orthographic variant. The PRDH form GAILLOU is canonical (confirmed against parish-register practice). The 1706 Chambalon clerk rendered the surname GAULTIN in the body of the quittance. Both refer to the same Pierre, husband of Marguerite Crête I, settled at Batiscan, where she died in 1734. Documented in the research log as a notarial spelling variant rather than a substantive identification conflict.
Resolved

DC-16: The Third Husband's Surname — Jourdain, not Soudain

1705 marriage contract (D-042), one reading: Pierre SOUDAIN, soldat
Nine other sources: Pierre JOURDAIN dit Bellerose
Resolution (Batch 9). The surname is Jourdain. The 1706 Notre-Dame de Québec marriage register, PRDH marriage record #67784, PRDH individual record #37271, the 1723 remarriage at Neuville, the 1738 burial, and the secondary attribution by Lebel and Laforest all read Jourdain — and decisively, the husband signed his own name "Pierre Jourdain" on the 1707 surveyor's partition (BAnQ CA301, S56, P149) and again on the 1712 lots-et-ventes receipt (BAnQ E1, S4, SS1, D224, P3). An autograph is the strongest available evidence of a man's own name, and the class of evidence least vulnerable to a later copyist. The "Soudain" reading is a single contestable interpretation of the contract's calligraphy: the lowercase J of the seventeenth-century notarial hand can resemble an S when the initial stroke is unusually angular. The dit name Bellerose attaches to Jourdain, confirmed by the 1707 Duprac quittance (D-065) and by Marie Crête's own 1722 burial act, which names her as wife of "the said Bellerose." Re-examination of the Chambalon protocol via Parchemin remains desirable but is no longer load-bearing. Lead L-29 closed.

The contract also carries later marginal annotations reading "Chevalier de St Louis" and "Généalogie de la militaire de St Louis." These are additions to the act, not statements within it, and what they signify has not been established; they are recorded as marginalia and no inference is drawn from them here.
Reopened

DC-17: 1706 Quittance — Who Holds the Second Quarter?

1706 Chambalon Quittance (D-040): names three sisters explicitly — Marguerite Crête (Mme Gaillou), Marie Françoise (Mme Delauney), and Marie Crête (Mme Jourdain)
Same document references 1/4 share: implies four total heirs
Hôtel-Dieu register (DC-20): Marie Françoise died 29 November 1702 — before her mother
Reopened in Batch 9. This entry formerly read: four heirs at one-quarter each, corresponding to the four surviving daughters — Marguerite I (Mme Gaillou), Marie Françoise (Mme Delauney), Marie the elder (Mme Jourdain), and Marie II the younger (Mme Lefebvre, implied via Jean Lefebvre's role as beau-frère advancing the funds), with the son Pierre already provided for by the 1693 Buisson fief transfer as avancement d'hoirie.

That reading no longer holds. Marie Françoise Crête died seven weeks before her mother; a person who predeceases the decedent does not inherit. The four-quarter structure is not in doubt, and neither is Pierre's exclusion. What is now open is the identity behind the "Mme Henri Delauney of Beauport" named in October 1706. Two readings remain possible: the name stands for Marie Françoise's children taking by representation, with their father acting for them; or Henri Delaunay had remarried by 1706 and the clerk recorded his then-current wife under the same style. Only the Chambalon minute can settle it. The sum advanced is forty-one livres: the act reads "de quarante vne liures," confirmed against the minute; a figure of fifty-one that had appeared in one derivative summary is withdrawn. See Lead L-35.
Resolved

DC-18: Jean Lefebvre's Full Name — Jean vs. Jean Baptiste

Working name across research: Jean Lefebvre dit Duchassenal
PRDH Family record for Marie Crête II × Lefebvre: JEAN BAPTISTE Lefebvre
Resolution: The full baptismal form is Jean Baptiste Lefebvre dit Duchassenal. Updated in the research log People Summary entry and in the Children's sheet. The biography retains "Jean Lefebvre" for narrative concision but introduces the full form on first mention. This is the same son-in-law who tended Marguerite during her terminal illness in winter 1702–03, who was named beau-frère in the 1706 Quittance, and who appears as one of the three Crête sons-in-law witnessing the 1693 marriage contract.
Resolved

DC-19: BAnQ Catalog Metadata — 1660 vs. 1666 for the Guion/Collin Sale

BAnQ catalog description for D-069 (1673 aveu et dénombrement): states the underlying Vachon sale as "August 4, 1660"
Body of D-069 and three independent corroborating acts (D-059, D-067, D-068): all confirm 4 August 1666
Resolution: Typing error in the typed copy or in BAnQ catalog metadata. The body of D-069 references "contract passé par devant nous dit notaire en datte du quatriesme jour d'aoust mil six cent soixante..." with the year completion partially obscured. Multiple independent primary sources cross-confirm 4 August 1666: the Vachon greffe sale itself (D-059), the 11 August 1666 Act of Faith and Homage (D-067), and the 5 November 1673 surveyor's division (D-068). The catalog "1660" is treated as a transcription error; the correct date is 1666.
Resolved

DC-20: Marie Françoise Crête's Death — 1702, not 1722

Working research log, formerly: died 17 November 1722, Hôtel-Dieu de Québec
Hôtel-Dieu du Précieux-Sang patient register + PRDH #19407: died 29 November 1702
Resolution (Batch 9). The register of the Hôtel-Dieu, in the roll of patients present on the first of November 1702, carries her admission on the twentieth with the marginal notation morte: "francoisse Crette fame de delauné agé de 43 ans de quebec — morte le 29 nov[em]bre." Admitted 20 November, dead nine days later. The stated age of forty-three is the clerk's approximation; measured from her 20 July 1660 birth she was forty-two years and four months. PRDH individual record #19407 agrees on both death and burial at 29 November 1702.

The 1722 reading, together with a burial date of 18 November that appears in no source, is withdrawn; both had been carried in the working log citing PRDH couple record #866, which gives 29 November 1702. The origin of the 1722 date has not been established and is not asserted here. Two consequences follow, and both are carried forward rather than absorbed: DC-17 is reopened above, and the "three Crête women in seven weeks" cluster asserted in the companion Marie Crête biography is restated as a two-death cluster of September and November 1722. A genuine seven-week cluster does exist, but in a different decade: Marie Françoise on 29 November 1702 and her mother on 15 January 1703, in the same smallpox winter, the daughter at the Quebec hospital and the mother at home in Beauport.
Open

DC-21: Louis Crête's Burial Date — 21 or 25 August 1685?

Saint-Laurent burial register: "le vingt-cinquième jour du mois d'aoust" — 25 August 1685
PRDH burial record #35618: 21 August 1685 for both death and burial
Status: The register is the earlier witness and its wording is unambiguous, so 25 August is used for the burial. The four-day interval formerly explained on the biography as the boat's remaining passage upriver rested on treating the database date as a date of death; the database in fact assigns it to the burial. The act states no date of death beyond "le jour mesme de son retour de France." Direct re-examination of the register page is the next action. A related minor conflict sits alongside it: the burial of the infant Marguerite II is read here as 18 May 1663 and by PRDH couple record #866 as 16 May. Both are addressed under Lead L-36.

Note on additional resolutions. Two further research findings — the documentation of Marie Crête's three successive marriages (Pepin 1670, Brideau ca. 1687, Jourdain dit Bellerose 1706) and the verification that earlier transcriptions of Marie's second husband should read "Brideau" — were captured during the same research arc but tracked in the People Summary and Children sheet of the research log rather than as separate Discrepancy entries. Both are fully sourced in the biography. The discrepancy count above — 21 tracked, 16 resolved, 5 open — reflects the working log's formal discrepancy register.

Open Questions — What to Search Next

The five open discrepancies are not failures of the research. They are honest acknowledgments that the documentary record, as it currently survives or as it has been examined, does not yet answer them. For each, the next research action is specified.

Three are Perche questions, set out below. The two opened in Batch 9 — the second quarter-share in the 1706 Quittance (DC-17) and the burial date of Louis Crête (DC-21) — differ from these in an important way: both are answerable from documents already identified and located. They need a reading, not a search. See Leads L-35 and L-36.

1. The Atlantic Crossing, 1652–1654

A specific year, port, and ship for Marguerite's voyage would close the most consequential remaining gap in her biography — the single act that turned her from a Perche girl into a New France colonist.
Next research action: Examine the Marine archive holdings of La Rochelle (Service Historique de la Défense, Rochefort), Dieppe (AD Seine-Maritime), and Honfleur (AD Calvados) for ship's rolls 1652–1654. Cross-reference the engagement contracts (contrats d'engagement) for Beauport-bound passengers in the same window. Specifically check the registers of the Compagnie des Cent-Associés and the Compagnie des Habitants. Search variants: Gaulin, Gollin, Gaullin, Gollins.

2. The Possible Pierre Gaulin Baptism, ca. 1620–1632

Pierre Gaulin is documented in Quebec as an adult — married at Château-Richer in 1664, dead at Ste-Famille in 1677 — but he does not appear in Godbout's 1925 transcription of the Saint-Martin register, which catalogues the other four siblings (Vincent, Marie, Marguerite, François).
Next research action: Examine the Saint-Martin-du-Vieux-Bellême parish register at the Archives départementales de l'Orne for 1620–1632 page-by-page (microfilm cote 3 NUMECRP/4E). Look specifically for any "Pierre" or "Pierres" entry as son of Vincent Gaulin/Gollin and Marie Boulemer. If absent, examine surrounding parishes (Saint-Aubin de Bellême, Saint-Pierre de Bellême) for the same period. Also cross-check whether Godbout's transcription was complete or selective.

3. Twin Status of Pierre and Marguerite

The twin claim, if valid, would mean Pierre was born 14 May 1627 alongside Marguerite. The absence of a record cannot disprove twin birth, but its presence would settle the question.
Next research action: Conditional on the outcome of question 2. If a Pierre Gaulin baptism exists in the Saint-Martin register, examine its date. A date of 14 May 1627 would confirm twin status; any other date would refute it. Concurrently, search burial records of Saint-Martin and Tourouvre for any "Pierre Gaulin" or "Pierre Gollin" 1620–1654 that might establish a birth year by inference (age at death).

Four Methodological Techniques Worth Naming

Four specific techniques produced disproportionate analytical value during this project. Each is worth naming because each can be applied to other research subjects.

1. Reading the Baptism Network

Ten Crête children were baptized between 1656 and 1671. Each register entry names the officiating priest, the godfather, and the godmother. Read individually, the entries record sacramental events. Read across fifteen years as a single corpus, they reveal a social network — who came to officiate, whose family stood as godparents, and how the household's social position changed.

The result was the recognition that the Crête-Giffard relationship was quasi-familial rather than patron-client. Robert Giffard personally emergency-baptized the infant Marie Françoise in 1660; his son Joseph and his granddaughter Françoise Juchereau stood as godparents. By 1666, the Grand Vicar of Bishop Laval was officiating, and the wife of the seigneur of Beauport was godmother to a child who took the seigneur's name. The 1666 acquisition of a parcel within the Dubuisson fief — transacted by Claude Guion and Catherine Collin of Île d'Orléans before Notary Paul Vachon, but ultimately rendering foi et hommage to the Giffard line as overseigneurs of the holding — viewed alongside this baptism record, becomes embedded in an existing close relationship with the seigneurial family rather than a transactional event between strangers.

The seigneurial documentary chain offers a parallel-track confirmation. Six years after the 1666 sacramental apex, Jean Crête transported himself to the principal door of the Beauport seigneurial castle and performed the full ritual of foi et hommage to Robert Giffard — one knee on the ground, bare-headed, no sword or spur, calling out three times to Monseigneur (D-067). Seven years later, with Robert dead and Joseph Giffard succeeded, Jean Crête rendered his aveu et dénombrement (D-069) detailing the parcel to the second generation of the Giffard line. The relationship documented through the baptismal register and the relationship documented through the seigneurial register are the same relationship, viewed from two different bureaucratic angles. Each strengthens the other.

The technique — reading a network across many register entries as if it were one document — transfers to any family with multiple baptisms in the same parish across several years.

2. Working with Negative Evidence

Several conclusions in this biography rest on the absence of records that should exist if a contrary claim were true.

Louise Crête, baptized 1670, does not appear in the 1681 census of the household. No burial record has been located, but the absence of any later mention establishes that she died before age ten. The absence is the evidence.

No son named "François Creste" appears in any Crête register entry before or after the 1666 census. The single recorded "François" in the 1666 enumeration, against the silence of every other source, becomes evidence not of a missing son but of a census-taker's recording error.

The technique also works in reverse. When a primary record arrives, it can convert what had been negative-evidence inference into a documented fact. Marguerite's illiteracy had been a working inference for years — supported by the absence of her signature on the surviving notarial acts where Jean signed in his own hand. The November 1693 marriage contract of son Pierre to Marthe Marcou (D-057, Notary Paul Vachon, certified copy by Duprac) closed the question directly. The third page of the contract names Marguerite Gollin explicitly among those who "declared not to know how to write or sign." Inference became record.

The contrast was confirmed directly by the 1673 aveu et dénombrement (D-069), the third page of which carries Jean Crête's signature in his own hand: "Jehan Creste." The literacy contrast within a single household becomes, in primary-source terms, gender-asymmetric: Jean signed his name; Marguerite did not. This is the documentary footprint of seventeenth-century habitant education in microcosm. Both pieces of evidence, the absent signature and the present one, now do BCG-grade work.

3. Triangulating Across Three Censuses

The 1666 royal census of New France is well-known. Less commonly examined together with it are the 1667 and 1681 enumerations of the same households. For the Crête family, all three exist.

Read across the fifteen years they span, the three censuses document not just continuity but trajectory: fifteen arpents under cultivation in 1667 became forty in 1681; six cattle became thirteen; and the household gained two firearms and added a servant. They also document a small consistency problem worth noting in its own right: the census-taker mis-recorded Marguerite's surname differently each time — Golin in 1666, Gosselin in 1667, Gaudin in 1681. The instability extended beyond the censuses: Notary Romain Becquet's sale to Denis Roberge of 14 April 1676 (D-061) renders the surname "Gosselin" in a notarial setting where stability would have been expected. Four distinct primary-source spellings across fifteen years — Golin, Gosselin (twice, in 1667 and 1676), Gaudin — with no surviving Crête-line act in which Marguerite herself rendered the spelling. The surname was the household's least stable variable across primary sources.

The technique is the lesson: never read a single census in isolation. A second enumeration of the same household is the cheapest cross-check available in seventeenth-century New France research.

4. Auditing the Index Against the Act

The fourth technique was the last to be applied and the most corrective. Every parish register act in the corpus was placed side by side with the database card that indexes it, and the two were compared field by field — names, dates, ages, places, participants.

The premise is that a card and the act it indexes are one witness, not two. Their agreement proves nothing, because the card is derived from the act; only their disagreement carries information. Read that way, the exercise is not a verification but a diagnostic: every divergence is either a transcription error in the index, a misreading in the working log, or a genuine ambiguity in the original hand — and each of those three requires a different response.

The audit caught a godparent surname (Godin read as Golin), two burial-date conflicts, a display artifact in which a database's English interface rendered a daughter's given name as "Married," and — most consequentially — a twenty-year error in a death date that had entered the working log attributed to a database record which says otherwise, and from there reached published conclusions on three pages of this site. It also closed the Soudain/Jourdain question by putting the contract reading next to the husband's own signature.

The cost of the technique is tedium; the return is that errors surface before a reviewer finds them. The lesson generalizes: the moment to audit an index against its source is after the conclusions are drafted, when there is something for a discrepancy to break.

Six Cases in Evidence Analysis

The Genealogical Proof Standard requires more than the assembly of sources — it requires the analysis and correlation of those sources into reasoned conclusions. The six cases that follow walk through specific claims in this biography step by step, showing how the evidence was weighed, how conflicts were resolved, and how each conclusion was reached. One of the six has since been partially withdrawn; it is kept in place, because a case that failed is more instructive than a case that never did.

Case 1 — Direct Evidence

Marguerite Gaulin's Parentage

Marguerite Gaulin (1627–1703) was the daughter of Vincent Gaulin and Marie Boulemer of Saint-Martin-du-Vieux-Bellême, Perche.

Sources Considered

  • 14 May 1627 — Saint-Martin-du-Vieux-Bellême baptism register, transcribed verbatim by Godbout (1925) and supplied as an image with Fichier Origine #241711: names Vincent Gaulin (Gollin) and Marie Boulemer as parents
  • 13 September 1654 — Notre-Dame de Québec marriage register: names Vincent Gaulin and Marie Bonnemer as parents of the bride, with Vincent unmarked and Marie explicitly "défunte"
  • Fichier Origine #241711 and GFNA #2351: derivative-primary indexes citing the same parentage
  • Lebel & Laforest and Gagné: secondary works citing the same parentage

Analysis and Correlation

Two independent primary sources name the same parental couple, twenty-seven years and an ocean apart: the Saint-Martin baptism of 1627 and the Notre-Dame de Québec marriage act of 1654. The surname appears with two orthographic variants — Boulemer in the Saint-Martin register, Bonnemer in the Quebec register — which Godbout's index explicitly cross-references as the same individual. That the parentage is recorded identically on both sides of the crossing, by clerks with no access to each other's registers, is what makes the identification secure.

Conflict Resolution

No primary or secondary source names different parents. The orthographic variance between Boulemer and Bonnemer is documented as DC-03 and resolved against the primary Saint-Martin register, with both forms acknowledged as referring to the same woman.

GPS Conclusion

Marguerite Gaulin's identification as daughter of Vincent Gaulin and Marie Boulemer is established by two independent primary sources recorded on separate continents, corroborated by index and secondary sources, with no conflicting evidence. The conclusion meets the Genealogical Proof Standard.

Case 2 — Indirect / Correlative Evidence

The Two Marguerite Crêtes

The Marguerite Crête who married Pierre Gaillou in 1678 and died at Batiscan in 1734 was Marguerite I (b. 1659), not Marguerite II (b. 1663). The infant Marguerite Crête buried in May 1663 was Marguerite II.

Sources Considered

  • 27 March 1659 — birth of Marguerite Crête (the elder); baptized 20 April at Giffard's house, Beauport
  • 30 March 1663 — birth of Marguerite Crête (the younger); baptized 1 April at Beauport
  • May 1663 — burial of "petite fille agée d'un mois et demy, fille de Jean Creste, habitant de Beauport"
  • 1666 royal census — lists "Marguerite Cresté, 7" alive in the Jean Crête household
  • 6 November 1678 — marriage record: Marguerite Crête × Pierre Gaillou
  • 4 October 1706 Chambalon Quittance (D-040) — names Marguerite Crête as Mme Gaillou of Batiscan, procuratrice
  • 12 October 1734 — burial of Marguerite Crête at Batiscan (Saint-François-Xavier)

Inferential Chain

The 1663 burial age — one and a half months — matches Marguerite II's 30 March 1663 birth, not Marguerite I's 1659 birth. The 1666 census shows a seven-year-old Marguerite alive in the household three years after the 1663 burial: the age is exactly consistent with Marguerite I (b. 1659, age 7 in 1666) and impossible for Marguerite II (who would have been 3 if alive). The 1678 marriage to Pierre Gaillou and the 1734 Batiscan burial both require a living adult Marguerite; her age at death in 1734 (approximately 75) is consistent with the 1659 birth.

Conflict Resolution

Earlier secondary sources had the case inverted, claiming the elder Marguerite died as infant and the younger married Gaillou. This was DC-05, resolved by the burial age and the 1666 census against the secondary literature. The exact day of the 1663 burial — 16 or 18 May — remains a minor open reading under DC-21 and does not bear on the identification.

GPS Conclusion

The inferential chain from burial age + census enumeration + adult life records is consistent only with Marguerite I as the survivor and Marguerite II as the 1663 infant burial. No alternative interpretation is consistent with all four primary records. The conclusion meets the Genealogical Proof Standard.

Case 3 — Negative Evidence Becoming Positive

Marguerite Gaulin's Illiteracy

Marguerite Gaulin was illiterate; Jean Crête was literate. The household exhibits the gender-asymmetric literacy pattern characteristic of seventeenth-century habitant Quebec.

Inferential Phase (before 1693)

Across multiple notarial acts in which Jean Crête signed in his own hand — the 1658 sale to Chevalier (D-058), the 1666 acts (D-059, D-067), the 1671 sale to Mourier (D-060), the 1685 partage (D-062), the 1689 donation (D-064) — Marguerite's signature is absent. She is named in the body of the act but does not sign. The pattern was suggestive but not conclusive: absence of a signature could indicate illiteracy, indisposition, absence from the act, or other factors.

Documentary Phase (1693 onward)

The 2 November 1693 marriage contract of son Pierre to Marthe Marcou (D-057), drafted by Notary Paul Vachon and certified-copied by Duprac, names Marguerite Gollin explicitly among those who "declared not to know how to write or sign." The previously inferential conclusion became a direct documentary finding.

Contrast Documented Directly

The 25 April 1673 aveu et dénombrement (D-069), page three, carries Jean Crête's signature in his own hand: "Jehan Creste." Jean's literacy is direct documentary fact in the same archival corpus as Marguerite's illiteracy — the two findings reinforce each other and together document the gender-asymmetric education pattern of the household.

Methodological Significance

This is a case where negative evidence functioned as a working hypothesis later confirmed by direct evidence. The discipline matters: had the 1693 contract never surfaced, the conclusion would have remained inferential and the biography's claim about Marguerite's illiteracy would have been written in calibrated probability terms. With the 1693 record in hand, the claim becomes documented fact.

GPS Conclusion

Both findings — Marguerite's illiteracy and Jean's literacy — are established by direct primary-source evidence. The earlier inferential phase exemplifies disciplined use of negative evidence: a hypothesis held appropriately, then confirmed when a direct record surfaced.

Case 4 — Network Argument from Correlation

The Crête-Giffard Quasi-Familial Relationship

The Crête-Giffard relationship was quasi-familial in character — a relationship of close personal bond and seigneurial intimacy — rather than ordinary patron-client or arms-length seigneurial commerce.

The Documentary Network (Eight Independent Acts)

  • 13 September 1654 — Jean Crête and Marguerite Gaulin married in the manor house of Sieur Robert Giffard (Beauport)
  • 20 April 1659 — Marguerite I baptized "chez Mr Giffard"; Father Paul Ragueneau officiating
  • 1 August 1660 — Marie Françoise Crête emergency-baptized at home by Robert Giffard personally when in danger of death; solemn ceremonies supplied later with Joseph Giffard (Robert's son) as godfather and Françoise Juchereau (Robert's granddaughter) as godmother
  • 2 May 1666 — Joseph Crête baptized; officiant Charles de Lauson de Charny (Grand Vicar of Bishop Laval); godfather Nicolas Juchereau Sieur de Saint-Denis (Robert's son-in-law); godmother Michelle Thérèse Nau, wife of Joseph Giffard, seigneur of Beauport; child named Joseph for the seigneur
  • 11 August 1666 — Jean Crête performs foi et hommage to Robert Giffard at the principal door of the seigneurial castle (D-067); the medieval ritual preserved intact
  • 25 April 1673aveu et dénombrement rendered to Joseph Giffard (D-069) after Robert's death and Joseph's succession
  • 5 November 1673 — Surveyor Jean Guyon's division (D-068) physically marks the boundary parcels
  • 1705 and 1712 — Continued seigneurial relationship through Nicolas Dupont (adjacent seigneur 1673; Pepin arbitrator 1705; Crête-Lefebvre rent tutor 1712), demonstrating that the seigneurial network around the Crête family continued past the Giffard line itself

The Correlative Argument

No single document above establishes a quasi-familial bond. Each one, read alone, could be explained by ordinary patron-client behavior — the marriage at the manor house, the baptisms with the seigneurial family at the font, the 1666 land transaction (now known to have been with Guion/Collin rather than Giffard directly), and the seigneurial obligations rendered formally. But when read across two registers and fifty-eight years, the documents do something different than each alone could do.

The 1660 emergency baptism, in particular, exceeds patron-client behavior. Robert Giffard personally administered the sacrament to a habitant's daughter in danger of death — an act of pastoral and personal intimacy, not a routine seigneurial gesture. The naming of the 1666 son Joseph, after the seigneur, with the seigneur's wife as godmother, signals more than acknowledgment of overlordship. The continuity of the seigneurial relationship across generations demonstrates a relational network that outlasted any single party.

The Counterargument and Its Limits

An alternative reading would hold that Robert Giffard simply baptized many habitant children in danger of death, that the Joseph naming was conventional, and that the seigneurial obligations were standard practice. The current research does not, however, document Robert Giffard personally administering emergency baptism to any other habitant household's children, nor does it document any other habitant-class Beauport baptism with both the seigneur's wife as godmother and the child named for the seigneur. The 1660 act and the 1666 baptism are documentary peculiarities specific to the Crête household.

Honesty requires naming the weakness in that argument: the absence of comparable records may reflect the limits of the search rather than the limits of the practice. No systematic survey of Beauport habitant baptisms 1650–1670 has been undertaken. The conclusion is therefore held as strong but revisable, and the counterfactual section below states exactly what would revise it.

GPS Conclusion

The quasi-familial reading is established by correlation across eight independent acts spanning two documentary registers (sacramental and seigneurial) and fifty-eight years (1654–1712). The patron-client alternative does not account for the documentary peculiarities specific to the Crête household. The conclusion meets the Genealogical Proof Standard while remaining open to revision should comparable documentation surface for other Beauport habitants of similar economic standing.

Case 5 — Structural Inference Across Documents

The Four-Heir Structure of Marguerite Gaulin's 1706 Succession

The 1706 Chambalon Quittance documents four heirs at one-quarter each to Marguerite Gaulin's succession; the surviving son Pierre had already received his share through the 1693 Buisson fief transfer.

The Apparent Tension

The 1706 Quittance (D-040) names three daughters explicitly: Marguerite Crête (Mme Gaillou, of Batiscan, procuratrice), Marie Françoise Crête (Mme Delauney), and Marie Crête (Mme Jourdain). The same document references "le quart" — one-quarter share — which implies four total heirs. The arithmetic does not close on the three named persons.

Correlation with Other Documents

The 2 November 1693 marriage contract of Pierre Crête (D-057) names three Crête sons-in-law as beaux-frères of the groom: Jean Brideau (Marie's second husband), Henry Delauney, and Jean Lefebvre. The PRDH Family record confirms Jean Baptiste Lefebvre as the husband of Marie Crête II (b. 1668, m. 22 October 1685 Beauport). The 1706 Quittance text explicitly identifies Jean Lefebvre as the beau-frère advancing the funds from which Marguerite Crête received her quarter share.

Pierre's Already-Received Share

The 1693 marriage contract documents that Jean and Marguerite granted Pierre six arpents of the Buisson fief at his marriage — "l'avancement d'hoirie" in customary law: an inter vivos donation that counted against his eventual succession share. This explains why he does not appear in the 1706 Quittance: he had already received his portion thirteen years earlier.

Where the Arithmetic Stopped Closing

This case formerly concluded that all five Crête survivors at Marguerite's death were accounted for: four daughters at one-quarter each, one son already advanced in 1693. The register of the Hôtel-Dieu has since established that Marie Françoise died 29 November 1702, seven weeks before her mother (DC-20). A person who predeceases the decedent does not inherit. One of the four named quarters therefore cannot belong to the person this case assigned it to, and that identification is withdrawn.

The failure is worth examining rather than deleting. Every step of the original reasoning was sound in its own terms: the fraction was read correctly, the sons-in-law were correctly identified, the customary-law treatment of Pierre's advancement was correct. What failed was an unexamined assumption — that a daughter named in a 1706 act was alive in 1706 — which no one thought to test because the act itself gave no reason to doubt it. Structural inferences are only as sound as the dates of their terms.

GPS Status — Partially Withdrawn

The four-quarter structure stands: D-040 states the fraction explicitly, and Pierre's exclusion is soundly explained by the 1693 transfer as avancement d'hoirie. What does not stand is the assignment of the second quarter to Marie Françoise. Either her children took by representation with Henri Delaunay acting for them, or Henri had remarried and the clerk named his current wife. DC-17 is reopened; Lead L-35 specifies the reading that would settle it.

Case 6 — Documentary Chain Across Two Continents

The Buisson Fief, 1634–1712 (Seventy-Eight Years)

The Buisson fief has a complete primary-source documentary chain from its 1634 origin at Mortagne, Perche, through Pierre Crête's 1712 rent receipt — image-verified end to end, save the 96-livre receipt of 1 June 1667 referenced in earlier research notes.

The Chain

  • 14 March 1634 — Robert Giffard grants the Buisson fief (1000 arpents) to Jean Guion before Notary Mathurin Roussel at Mortagne, Perche, France [cited in D-069]
  • By 1666 — Jean Guion and Mathurine Robin both deceased [D-067, D-069]
  • 4 August 1666 — Claude Guion (son and heir) and Catherine Collin sell the parcel to Jean Crête before Notary Paul Vachon (D-059)
  • 11 August 1666 — Jean Crête performs foi et hommage to Robert Giffard at the seigneurial castle (D-067)
  • 1 June 1667 — 96-livre receipt referenced in earlier research notes [unretrieved — L-33]
  • April 1668 — Robert Giffard dies; Joseph Giffard succeeds [historical record]
  • 25 April 1673 — Jean Crête's aveu et dénombrement to Joseph Giffard (D-069)
  • 5 November 1673 — Surveyor Jean Guyon records the physical division (D-068)
  • 29 July 1693 — A separate Chambalon sale by Sieur des Méloizes to Pierre Crête, Jean Baptiste Lefebvre, and Jean Baugis [referenced in D-070; underlying contract not yet retrieved — L-34]
  • 2 November 1693 — Jean and Marguerite grant Pierre Crête six arpents of the Buisson fief at his marriage (D-057)
  • 31 July 1712 (with 18 January 1716 endorsement) — Nicolas Dupont, as tutor of the des Méloizes minor heirs, acknowledges receipt of rent from Pierre Crête for the 1693 land (D-070)

What the Chain Demonstrates

This is a documentary chain across two continents (Perche to New France) and seventy-eight years, with eleven nodes named, of which nine are image-verified primary sources presently in the research log. The chain is structurally complete: every transfer of right has its instrument, every renewal of seigneurial obligation has its act, and every change of personnel (Robert → Joseph Giffard; Jean → Pierre Crête; Sieur des Méloizes → minor heirs under Nicolas Dupont) is documented at its juncture.

Reasonably Exhaustive Search

The BCG requirement of reasonably exhaustive search is met for the Buisson fief documentary chain. The two unretrieved elements (the 96-livre receipt and the 29 July 1693 joint sale) are named, their archival series identified, and the search continues. The biography's claims about the Buisson fief stand on a primary-source foundation that the typical New France habitant family record does not possess.

GPS Conclusion

The Buisson fief chain demonstrates Reasonably Exhaustive Search, Complete Source Citations, Analysis and Correlation across documents, and Resolution of the Giffard-vs-Guion/Collin vendor question. It is a portfolio-grade example of multi-document genealogical reasoning.

Source Weighing — Selected Claims

For four key claims in the biography, the sources contributing to the conclusion are weighed explicitly. The evidentiary weight reflects both the tier of the source and the proximity to the event being recorded. Where sources conflict, the resolution rests on the highest-weight evidence aligned with the analytical record.

Claim 1: Marguerite Gaulin was the daughter of Vincent Gaulin and Marie Boulemer.

Source Tier Date Weight Position
Saint-Martin baptism act (Fichier Origine image; Godbout 1925 transcription) Primary 1627 Highest Vincent + Marie Boulemer named
Notre-Dame de Québec marriage register Primary 1654 Highest Vincent + Marie Bonnemer named (variant spelling); Marie marked défunte
Fichier Origine #241711; GFNA #2351 Derivative-Primary (index) Modern Supporting Confirms primary citations
Lebel/Laforest; Gagné Secondary (published) 1979, 2002 Corroborating Aligns with primary
Conclusion Established — two independent primary sources on two continents, no conflict

Claim 2: Marguerite Gaulin was born in May 1627 (DC-01).

Source Tier Date Weight Position
Saint-Martin baptism act (image via Fichier Origine; Godbout transcription verbatim) Primary 1627 Highest Reads "Le quatorzième de may aud[it] an 1627"
Beauport burial register, 1703 Primary 1703 High Age "environ soixante et quinze ans" — exactly consistent with May 1627
Fichier Origine #241711 Derivative-Primary Modern High Cites the same date and parentage
Lebel & Laforest Secondary 1979 Superseded States "ca. 1625" — superseded by primary
Conclusion Resolved — baptism act gives 14 May 1627; the 1703 burial age independently corroborates

Claim 3: The 1666 Buisson fief parcel was sold by Claude Guion and Catherine Collin, not by the Giffard family (DC-14).

Source Tier Date Weight Position
Vachon Vol. II p. 21 (D-059) Primary (notarial citation) 1666 Highest Names Guion/Collin as vendors directly

Aveu et Dénombrement (D-069) Primary 1673 Highest Restates the Guion provenance with full chain back to Jean Guion 1634
Earlier working narrative Inferential Superseded Had attributed sale to Joseph Giffard — incorrect
Conclusion Resolved — three independent primary acts confirm Guion/Collin as vendors; earlier inference corrected against the primary record

Claim 4: Marie Crête's third husband was Pierre Jourdain dit Bellerose, not Pierre Soudain (DC-16).

Source Tier Date Weight Position
1707 surveyor's partition — the husband's own signature Primary (autograph) 1707 Highest Signs "Pierre Jourdain"

1705 Chambalon contract, one reading Primary (contested calligraphy) 1705 Superseded Read by some as "Soudain" — a lowercase J resembling an S
Conclusion Resolved — two autographs of the man's own name outweigh a single contested reading of a clerk's hand

Counterfactual Reasoning — What Would Falsify These Conclusions

A BCG-grade conclusion is not only one that the evidence supports — it is also one that has been tested against the question of what alternative evidence could overturn it. For the three most consequential conclusions in this biography, the falsification conditions are named explicitly.

Counterfactual 1: The Jourdain Reading (DC-16)

Resolved conclusion — the third husband of Marie Crête was Pierre Jourdain dit Bellerose. The "Soudain" reading of the 1705 marriage contract is withdrawn.
What Would Falsify This
  • A re-examination of the Chambalon protocol establishing that the contract's hand is unambiguously S and not J, together with a second contemporaneous act naming a distinct Pierre Soudain married to Marie Crête
  • Evidence that the 1707 partition and 1712 receipt signatures belong to a different man — a second Pierre Jourdain at Quebec in the same decade, married to a different woman
Why the Reading Holds

Nine sources read Jourdain against one that has been read as Soudain, and two of the nine are the husband's own autographs on property records five years apart. A signature is the strongest evidence of a man's own name that a seventeenth-century record can supply, and it is the class of evidence least vulnerable to a later copyist's misreading. The contested contract reading is explicable as a calligraphic ambiguity in a hand where the lowercase J and S converge.

Current Evidence Weight
Established by Preponderance and Autograph

Lead L-29 is closed. Parchemin re-examination of the 1705 contract remains desirable for completeness but is no longer load-bearing on the identification.

Counterfactual 2: The Two Marguerite Crêtes (DC-05)

Established conclusion — Marguerite I (b. 1659) survived and married Pierre Gaillou; Marguerite II (b. 1663) died as an infant.
What Would Falsify This
  • A primary record after 1663 explicitly naming a Marguerite Crête born 1663 in adult life — would invert the conclusion
  • A burial record for Marguerite I before 1678 — would require a third Marguerite to explain the 1678 marriage to Gaillou
  • A 1666 census reading showing a 3-year-old Marguerite instead of a 7-year-old — would force a re-reading of the census
Why the Alternative Is Implausible

The 1666 census entry for "Marguerite Cresté, 7" is unambiguous. The 1663 burial of "petite fille agée d'un mois et demy" matches a 30 March 1663 birth exactly — Marguerite II. The 1734 Batiscan burial of Marguerite Crête (Mme Gaillou) at approximately age 75 is consistent with the 1659 birth and not with 1663. The four independent primary records align on Marguerite I as survivor, Marguerite II as infant burial.

Current Evidence Weight
Established Beyond Reasonable Doubt

No alternative interpretation is consistent with all four primary records. Overturning it would require a substantial documentary find that contradicts existing primary evidence — not merely additional context.

Counterfactual 3: The Crête-Giffard Quasi-Familial Reading

Network-correlative conclusion — the Crête-Giffard relationship was quasi-familial, not ordinary patron-client.
What Would Falsify This
  • Discovery that Robert Giffard personally emergency-baptized multiple habitant children of similar economic standing — would suggest the 1660 act was routine seigneurial pastoral behavior rather than a peculiarity
  • Discovery that Joseph Giffard's wife stood as godmother to many habitant children of similar economic standing — would weaken the 1666 baptism's exceptional reading
  • A record of Crête conflict with Giffard, or of rapid distancing in the 1670s after the 1668 death of Robert — would suggest the relationship was contingent rather than enduring
Why the Network Reading Currently Holds

The current research has not located evidence of Robert Giffard performing emergency baptism for any other habitant household, nor any other Beauport baptism with both the seigneur's wife as godmother and the child named for the seigneur. The 1673 aveu et dénombrement demonstrates the relationship continued into the second Giffard generation. The Nicolas Dupont continuity through 1712 shows the social network extending beyond the Giffard line itself. The eight independent documents reinforce one another; none alone establishes the conclusion, but their correlation does.

The honest limit: no systematic survey of Beauport habitant baptisms 1650–1670 has been undertaken, so the peculiarity of these acts is asserted against an unsurveyed field. This is the weakest joint in the argument and is named as such.

Current Evidence Weight
Established by Correlation — Open to Revision

The conclusion is appropriately strong for current evidence but remains open to revision should comparable documentation surface for other Beauport habitants of similar economic standing. This is the appropriate epistemic posture for network arguments.

Research Planning — What Remains and Where to Search

A Reasonably Exhaustive Search is not the same thing as a finished search. For each open question and pending lead, the next research action is specified, the archival series identified, and the priority assigned. This is the discipline of named-next-step research planning: every open question has a search.

High Priority — Readings That Would Close Open Discrepancies
High

L-35 — The Chambalon Minute of 4 October 1706 (DC-17)

One reading in this act requires direct re-examination: the identity of the "Mme Henri Delauney of Beauport" named as a quarter-share heir, given that Marie Françoise died seven weeks before her mother. The sum advanced is settled at forty-one livres against the minute.

Next research action: Determine from the Chambalon minute of October 1706 whether the act names Marie Françoise's children by representation, or a second wife of Henri Delaunay. Concurrently search the Beauport register for a Delaunay remarriage 1703–1706, and the Beauport baptisms 1680–1702 for the Delaunay children who would take by representation.
High

DC-11 — Marguerite's Atlantic Crossing Year, 1652–1654

The single most consequential gap in the biography — the act that turned a Perche girl into a New France colonist remains undocumented in its details (year, port, ship, fellow passengers).

Next research action: Examine Marine archive holdings: Service Historique de la Défense Rochefort (La Rochelle departures); AD Seine-Maritime (Dieppe); AD Calvados (Honfleur). Cross-reference engagement contracts (contrats d'engagement) for Beauport-bound passengers 1652–1654. Check Compagnie des Cent-Associés and Compagnie des Habitants rolls. Search variants: Gaulin, Gollin, Gaullin, Gollins.
High

DC-12 — The Possible Pierre Gaulin Baptism, ca. 1620–1632

Pierre Gaulin's adult Quebec life is documented; his baptism does not appear in Godbout's 1925 transcription of the Saint-Martin register. Whether absent, omitted, or lost remains undetermined.

Next research action: Examine Saint-Martin-du-Vieux-Bellême parish register at the Archives départementales de l'Orne, 1620–1632, page-by-page (microfilm cote 3 NUMECRP/4E). Cross-check Saint-Aubin de Bellême and Saint-Pierre de Bellême parishes for the same period. Confirm whether Godbout's transcription was complete or selective.
High

DC-13 — Pierre Gaulin's Twin Status with Marguerite

Conditional on DC-12. If Pierre existed, his twin status with Marguerite (14 May 1627) is testable. Absence of any record cannot disprove twin birth, but its presence with a 14 May 1627 date would settle the question.

Next research action: Conditional on outcome of DC-12. If a Pierre Gaulin baptism exists, examine its date. A date of 14 May 1627 confirms twin status; any other date refutes it. Concurrently, search burials at Saint-Martin and Tourouvre for "Pierre Gaulin" or "Pierre Gollin" 1620–1654 that might establish birth year by inference (age at death).

L-26 — Image Acquisition for the Eight Parchemin Citations

D-058 through D-065 are currently CITATION VERIFIED from the Parchemin database. Primary images are needed for BCG portfolio review.

Next research action: Order or photograph from BAnQ: Vachon 9 Dec 1658 (D-058), Vachon 4 Aug 1666 (D-059 — particularly critical as the corrective source for the Buisson fief vendor), Vachon 22 Oct 1671 (D-060), Becquet 14 Apr 1676 (D-061), Vachon 30 Jun 1685 partage of Gaulin estate (D-062), Vachon 14 Jul 1685 quittance to Bareau (D-063), Vachon 31 Jan 1689 donation to Pierre (D-064), Duprac 25 Apr 1707 quittance (D-065).
High

L-30 — Trottain Procuration of 27 September 1706

Named directly in the 1706 Chambalon Quittance (D-040). Provides the chain of authority for Marguerite Crête I's appearance at Quebec by procuration.

Next research action: Order from BAnQ Trois-Rivières the Trottain greffe September 1706. Notary François Trottain dit Saint-Surin practiced at Batiscan.
Medium Priority — Specific Documentary Gaps
Medium

L-36 — Saint-Laurent Burial Register, August 1685 (DC-21)

Confirm the burial date of Louis Crête: the register reads 25 August, PRDH #35618 carries 21 August for both death and burial.

Next research action: Re-read the Saint-Laurent (Île d'Orléans) register page for August 1685 via the Drouin Collection. While there, check the Notre-Dame de Québec burial page for May 1663 against the 16-versus-18 May reading for the infant Marguerite II.
Medium

L-37 — The La Rochelle Marriage of Louis Crête, 28 May 1685 (DC-06)

The marriage is recorded in PRDH Couple #5533 as taking place in France; the Saint-Sauveur attribution comes from the secondary literature. No register image has been retrieved.

Next research action: Search the Archives départementales de la Charente-Maritime, Saint-Sauveur de La Rochelle parish register, May 1685. If absent, check Notre-Dame-de-Cogne (Madeleine Briault's own parish) for the same month.
Medium

L-33 — 96-Livre Receipt of 1 June 1667

One of two remaining unretrieved elements of the Buisson fief documentary chain. Referenced in earlier research notes; not yet primary-verified.

Next research action: Search the BAnQ Vachon greffe for June 1667 and the Lordships Collection series P240/D26 (which holds D-067 and D-069 in the same series numbering). The receipt may be archived adjacent to the existing acts.
Medium

L-34 — 29 July 1693 Chambalon Joint Sale

Underlying contract referenced in D-070: Sieur des Méloizes sold to Pierre Crête, Jean Baptiste Lefebvre, and Jean Baugis. Three months before Pierre's 2 November 1693 marriage.

Next research action: Order the Chambalon greffe July 1693 from BAnQ. Documents the Crête-Lefebvre joint partnership and helps identify Sieur des Méloizes (possibly of the Renaud d'Avène des Méloizes seigneurial line).
Medium

L-31 — Marriage Record of Marguerite I × Pierre Gaillou, 6 November 1678

Verify primary surname spelling: GAILLOU (PRDH canonical) versus GAULTIN (1706 Chambalon variant). PRDH couple record #866 gives the place as lieu indéterminé, so the parish is itself unestablished.

Next research action: Locate the 1678 parish register marriage entry through PRDH or BAnQ. Confirm GAILLOU as primary; document GAULTIN as orthographic variant; establish the parish.
Medium

L-27 — Identify "Jean Gaulin of Saint-Bernard, Charlesbourg"

Named in 1685 Vachon quittance (D-063) alongside Jean Crête, Marguerite Gaulin, and Marie Rocheron. Likely Marguerite's nephew or another Gaulin sibling-line relative.

Next research action: Search PRDH for "Jean Gaulin" associated with Saint-Bernard (Charlesbourg) parish in the 1680s. Cross-reference against the François Gaulin orphans named in D-062.
Low Priority — Onomastic Curiosity
Low

L-32 — Collin / Gollin / Gaulin Surname-Root Check

Catherine Collin (1666 Buisson fief co-vendor) and Marguerite Gollin / Gaulin share a surname root. Possible distant kinship.

Next research action: Cross-reference Catherine Collin's parentage and origin in PRDH / Tanguay / Gauthier against the Vincent Gaulin / Marie Boulemer line of Saint-Martin-du-Vieux-Bellême. Likely separate lines; an unexpected kinship would be a low-probability but high-interest find.

L-28 — The 1673 Aveu et Dénombrement

Closed via D-069 (image-verified). The 1673 aveu now anchors the Buisson fief documentary chain back to the 1634 Mortagne origin. The remaining 96-livre receipt of 1 June 1667 is split out as L-33.

Closed

L-29 — Pierre Soudain dit Bellerose Verification

Closed in Batch 9. The identification resolved to Pierre Jourdain dit Bellerose on the husband's own signed autographs of 1707 and 1712, together with eight further sources reading Jourdain (DC-16). Parchemin re-examination of the 1705 contract remains desirable for completeness but is no longer load-bearing.

Fifty-seven of these sources are reproduced as images in a complete visual archive, maintained separately and available to colleagues on request. The remainder are citation-verified without images — chiefly the eight Parchemin-cited notarial acts tracked above as L-26.

Of the research leads still pending, the highest-priority items are the five open discrepancies above; the re-reading of the 1706 Chambalon minute that would settle the second quarter-share and the disputed sum (L-35); image acquisition for the eight Parchemin-cited notarial documents (D-058 through D-065 — Vachon, Becquet, and Duprac greffes, 1658–1707); the procuration of 27 September 1706 before Notary François Trottain at Batiscan; the 96-livre receipt of 1 June 1667 (L-33); the 29 July 1693 Chambalon joint sale referenced in D-070; and the La Rochelle register for Louis Crête's 1685 marriage (L-37). None of the pending leads call into question the central documented arc of Marguerite Gaulin's life.

Closing Reflection

A documentary biography is not the same thing as a biography. It is a biography that shows its sources, names its uncertainties, and submits its claims to a discipline of verification. The story of Marguerite Gaulin survives in the records that survive. Where they speak, the biography speaks with them. Where they are silent, the biography is silent or admits the silence.

The reader who has followed this far understands what the biography asks them to trust and what it asks them only to consider. The Atlantic crossing of 1654 is documented in its outcome — she was in Beauport by September — but its details (port, ship, date, fellow passengers) are not. The marriage in Sieur Giffard's manor house is documented exhaustively, down to the priest's name. The ten children are documented from baptism to death wherever the registers survive. The relationship to Robert Giffard is documented not through a single record but through a network of baptisms, fief transactions, and witnessing relationships that no one of these documents would carry alone.

For the descendant who wants the story, the biography is the answer. For the genealogist who wants the verification, this page is. Together, they are what a Storyline Genealogy project is meant to deliver: research worked to a professional standard, presented as a life.
