Tutelle account rendered by Paul Guilbault père, 22 July 1820.

The Challenge

The same archive that documents his brother Gabriel as a voyageur for over two decades records Paul Guilbault as nothing but a mason and a farmer. If you searched only the Quebec parish records, you would never know he left.

Paul Guilbault was born at Notre-Dame-de-Montréal on 23 April 1761 — one year before his brother Gabriel. They had the same parents: Gabriel Guilbault and Marie Charlotte Morin of L’Assomption. And in 1820, they paddled the same trade routes for the same employer, side by side, in their late fifties.

None of this appears in any Quebec parish record bearing Paul’s name.

What the Records Show

A systematic review of every Quebec document touching Paul Guilbault père yields five occupation designations across nearly four decades. Voyageur is not among them:

1796 agriculteur — daughter Judith’s baptism, St-Paul-de-Lavaltrie, 12 Sep 1796
1798 maçon — burial of Anonyme (male), St-Paul-de-Lavaltrie, 17 Mar 1798
1798 laboureur — joint burial of twin infants, St-Paul-de-Lavaltrie, 25 Nov 1798
1800 laboureur — daughter Rose’s baptism, St-Paul-de-Lavaltrie, 13 May 1800
c.1800

1801
[F.5.1, fo.115: Paul Gibeau signs NWC servants’ contract under Roderick McKenzie — milieu, 450 livres, Great Slave Lake, return Montréal — while Quebec records simultaneously identify him as maçon and laboureur. The invisibility is complete from the beginning.]
1801 maçon — baptism of Olivier (d. same day) and daughter Marie-Angélique, St-Paul-de-Lavaltrie, 22–23 Feb 1801
1802 maçon et laboureur — daughter Sophie I’s baptism and burial, St-Paul-de-Lavaltrie. ★ The only record combining both designations.
1807 cultivateur — daughter Lucie’s baptism, St-Paul-de-Lavaltrie, 2 Nov 1807
1815 maçon — daughter Ursule’s marriage, St-Paul-de-Lavaltrie, 25 Sep 1815. Last Quebec record before NWC departure.
1819 cultivateur — daughter Judith’s marriage, St-Paul-de-Lavaltrie, 8 Feb 1819
1820

1821
[tutelle rendered Jul 1820 — last act before NWC departure; HBCA F.4/37 & F.4/32 record service at Athabasca; account SETTLED 1821]
1821 laboureur — daughter Rose’s marriage, St-Paul-de-Lavaltrie, 16 Oct 1821. First post-return Quebec record.
1831 cultivateur — Paul’s burial: “Paul Guilbau décédé avant hier agé de soixante et treize ans… cultivateur”

The word voyageur does not appear once. In contrast, his brother Gabriel is identified as “voyageur et maintenant agriculteur” in a single 1798 baptism record — a dual designation that guided researchers directly to the NWC archives.

The Last Legal Act Before Departure

On 22 July 1820, Paul appeared before Notary Barthélémy Joliette to render the guardianship accounts for the five orphaned children of his brother Louis Guilbault. On the same day, his son Joseph paid the balance of a debt owed to his father: 79 livres and 12 sols. Father and son settling accounts on the same afternoon. Paul departed for the pays d’en haut shortly after.

What Silence Cannot Answer

Without the Hudson’s Bay Company Archives, Paul Guilbault père is invisible to history as anything other than a mason-turned-farmer. The NWC account books and servants’ contracts are not corroborating evidence of a known voyageur. They are the entire case.

HBCA NWC Account Books Name Index showing Paul Guilbeau entries.

The Breakthrough

Two entries in the HBCA Name Index lead to two volumes — F.4/37 and F.4/32. On page 117 of the Athabasca blotter, three words change everything: By Lieut Franklin.
1. The Name Index: Two Entries
Verdict: Paul Guilbault located in the Athabasca department Strong The HBCA NWC Account Books Name Index returns Paul Guilbeau / Guilbault in two volumes: F.4/37 (Athabasca general blotter, 1820–1821) and F.4/32 (NWC general ledger). His brother Gabriel Guilbault appears in three volumes. The brothers appear at adjacent reference numbers in the Lac La Pluie index — placed at the same post in the same year.
2. F.4/37, Page 106 — Debit Account, Athabasca 1820
Verdict: Active interior service confirmed; pemmican purchase places him on the route Strong Page 106 records Paul Guilbeau’s debit entries for the 1820 season: 200 pounds of rendered fat pemmican — travel food confirming active interior movement — and a transfer entry of 179.10 livres from Fort William, the NWC’s inland Lake Superior depot and staging point for all Athabasca brigades.
3. F.4/37, Page 117 — The Key Record
Verdict: Employment confirmed; Franklin connection documented; wages and settlement established Strong Page 117 is the heart of the case. Between the balance forward and the 1821 wage entry:
By Lieut Franklin  —  100
To Sundries at Lac La Pluie  —  16
1821 By Wages  —  617.14
To Balance  —  669.14 / 669.14
1821 By Balance  —  617.14
SETTLED

The 100-livre credit “By Lieut Franklin” corresponds to Lieutenant John Franklin’s First Polar Expedition, which recruited voyageurs at Fort Chipewyan in spring 1820. Franklin’s own Narrative (1823) documents his recruitment of NWC men and payments made on the Company’s account. Paul’s NWC wages: 617 livres and 14 sols, settled in 1821.

4. F.4/32, p.396 — NWC Company Ledger
Verdict: Company-wide accounting confirms wages, merchandise, and brother placement Strong F.4/32, the main NWC company ledger, records Paul Guilbeau’s account at page 396: merchandise debits totaling 446 livres; wages credit 350 livres; balance 96 livres carried to 1821. His brother Gabriel Guilbault appears at page 414 in the same volume — eighteen pages apart, independently confirming the brothers worked for the same employer in the same period.
1820 To Merch. Books  —  180.2
     To Cloth Kitchen  —  15 —
     To Sundries R. Books  —  248.11
                            446 —
1821 To Balance  —  96 —

1821 By Wages  —  350 —
     By Balance  —  96 —
                            446 —

The 350-livre wage figure in the company ledger and the 617-livre figure in the Athabasca blotter are not contradictory — they represent different accounting levels tracking the same service period. F.4/32 is the company-wide master ledger; F.4/37 is the district-level blotter that includes additional credits (the 100-livre Franklin payment) and transfers between posts. Together, the two volumes provide independent, cross-referencing documentation of Paul’s NWC employment.

5. F.5.1, fo.115 — The Earliest Contract: c.1800–1801
Verdict: NWC service confirmed twenty years before the account books Strong HBCA F.5.1, folio 115 — a fully executed NWC servants’ contract — places Paul in the North West Company’s engagement system approximately twenty years before the F.4 account books open in his name. Agent: Roderick McKenzie. Role: milieu. Wages: 450 livres. Route: Lac la Pluie → Athabasca → Great Slave Lake. Return: Montréal. A blank pre-printed form bearing his name (F.5.1, page 76) precedes the filled contract, establishing he was known to the company before the engagement was finalized. Folio 114 is noted missing. Age at signing: approximately 39–40.
6. F.5.3, pp.32–33 — The Final Contract: 22 May 1821
Verdict: Career extends through the NWC’s dissolution and into the HBC merger period Strong Signed two months after the NWC–HBC merger of March 1821. Agent: Samuel Black — one of the NWC’s most formidable Athabasca partners. Witnesses: William McGillivray Jr. and James Hill. Role: milieu de picheur, 500 livres. Winter post: Lac d’Athabasca. Return: Montréal. A specific clause exempts him from portage carrying at departure. The summary notation on the following page: for 1822 — the engagement was intended to carry forward into the reorganized HBC’s first full year of operation. Signed by mark, as always. Age at signing: approximately 60.
The Franklin Connection — Evidence Assessment

Probable corroboration; verification path documented

“By Lieut Franklin — 100” in Paul’s NWC account is consistent with Franklin’s documented activity at Fort Chipewyan in spring 1820. His Narrative, Chapter IV, records the recruitment of NWC voyageurs and payments made on the Company’s account during this period.

This connection has not yet been independently verified through Admiralty records at the UK National Archives (ADM 1/2414) or Franklin’s original field notebooks at the Scott Polar Research Institute (SPRI MS 248, Cambridge). This case study presents the connection as probable and frames the verification status as pending.

1828 notarial act: Pierre Lorion life annuity for Paul Guilbault père.

The Result

The NWC account books document where Paul went and what he earned. The notarial records document what he did with it. Together, they tell the story of a man who returned from the pays d’en haut and converted his wages into a retirement income that lasted until his death.
What the Records Establish

Paul Guilbault père was employed by the North West Company in the Athabasca department during the 1820–1821 season. His wages were 617 livres and 14 sols in the district blotter (F.4/37) and 350 livres in the company-wide ledger (F.4/32, p.396) — two independent accounting levels documenting the same service. A 100-livre credit from Lieutenant John Franklin’s expedition was applied to his account at Fort Chipewyan in spring 1820. His account was formally settled at the NWC–HBC merger in 1821.

His brother Gabriel worked the same posts, for the same employer, at the same time. Both men were in their late fifties. Both had their accounts settled in 1821. The parallel — which would be invisible if only the Quebec parish records were consulted — becomes visible only through the HBCA archive.

The Post-Return Financial Record

Paul is first documented in Quebec after NWC service by October 1821 — his daughter Rose’s marriage at St-Paul-de-Lavaltrie, where he appears as laboureur, just months after the NWC account was settled.

  • April 1827: Joseph Lorion received 228 livres from Paul and constituted a life annuity of 10 minots of wheat per year, secured by mortgage on Kildare Township land. Notary: Jean-Olivier Leblanc.
  • June 1828: Pierre Lorion received 200 livres and constituted a life annuity of 4 minots of wheat per year, secured by mortgage on the Lorion farm. Same notary.
  • July 1832: Paul fils appeared and received full repayment of the Joseph Lorion capital — 228 livres plus outstanding rente — giving final discharge.

Total capital deployed from NWC wages: 428 livres. Annual grain income at peak: 14 minots of wheat from two secured farm loans. Both annuities were extinguished at Paul’s death on 2 January 1831.

What This Case Means

Paul Guilbault’s case is not unusual. It is the norm. The men who signed NWC and HBC contracts at interior posts returned to their Quebec parishes and resumed their farming identities. The priests recorded what they saw: a farmer, a mason, a laborer. The canoe routes were invisible to the parish record system.

The implication for genealogical research is direct: a Quebec ancestor listed only as cultivateur or maçon in every surviving record is not thereby proven to have never been a voyageur. The HBCA archive — 3,700 names in the NWC Name Index alone — holds the possibility of a different answer.

Researcher’s Note

Paul Guilbault père is the great-great-great-great-granduncle of the researcher — the brother of Gabriel Guilbault père, who is her 4th-great-grandfather through the line: Gabriel & Marie Josephte → Gabriel fils (1791) → Evangeliste (1845) → Elisabeth Emma Guilbault Gilbert (1883) → Thomas Eugene Hamall (1904) → Thomas Kenny Hamall (1932) → Researcher. The brothers’ parallel NWC service connects two branches of the Guilbault family through the same years in the pays d’en haut.

Open Research Questions

The Franklin connection awaits verification at ADM 1/2414, UK National Archives, and SPRI MS 248, Cambridge. F.5 servants’ contracts between F.5.1 (1798) and F.5.3 (1815–1822) have not been searched for intermediate Paul Guilbault engagements.

Full Methodology

How to find a voyageur the parish records erased — the complete research process, from occupation gap to HBCA archive to post-return confirmation

The Central Question This Case Addresses

What do you do when the standard sources — parish records, census, notarial documents — are entirely consistent with each other, entirely silent on a specific chapter of a man’s life, and wrong about the complete picture? Paul Guilbault’s case illustrates the systematic use of negative evidence, occupational gap analysis, and institutional archive research to recover what the familiar record systems cannot show.

Step One

Identify the Occupational Gap

Paul Guilbault is last listed as maçon in September 1815 and reappears as cultivateur in February 1819. Between those dates there are no baptisms, burials, or other parish events to place him continuously in Quebec. In July 1820, he rendered the tutelle for his brother Louis’s children — an act with the character of a final settlement before a prolonged absence. His son Joseph paid a debt on the same day. These are the actions of a man who is leaving.

Step Two

Access the HBCA Name Index

The HBCA NWC Account Books Name Index covers over 3,700 employee names from the NWC period (F.4 series). Search under all surname variants: Guilbault, Guilbeau, Gibault, Gibeault. A search for the partial string “guilb” returns all variants. For Paul, the Name Index returned two hits: F.4/37 (Athabasca general blotter) and F.4/32 (NWC general ledger). These are the access points that open the case.

Step Three

Read the Account Book Entries

NWC account books are structured as double-entry ledgers: debit entries on the left, credit entries on the right. Paul’s pemmican entry — 200 pounds of rendered fat pemmican at the Athabasca post — is not a random purchase. Pemmican was the travel food of the interior brigades. The “To A/C from Fort William” entry establishes that Paul’s account began at the Fort William depot, the NWC’s great inland hub where all Athabasca brigades assembled.

Step Four

Confirm Identity Through Cross-Reference

For Paul, identity confirmation comes from the F.4/37 entry “To Sundries at Lac La Pluie — 16,” which independently corroborates the F.4/32 Lac La Pluie account entry. The geographic progression — Lac La Pluie → Fort William → Athabasca — matches the documented NWC brigade route. The family connection to Gabriel, whose identity is independently confirmed through the 188-livre linking balance, provides an additional layer of corroboration.

Step Five

Document the Post-Return Evidence

For Paul, the first post-return documentation is Rose’s marriage register at St-Paul-de-Lavaltrie on 16 October 1821 — where he is listed as laboureur. The April 1827 Joseph Lorion annuity begins his documented post-return financial activity. Paul did not return empty-handed: he came back with capital sufficient to fund two secured grain annuities and to live as a financially independent cultivateur for four years before his death in January 1831.

Step Six

Apply the Negative Evidence Standard

The BCG Genealogical Proof Standard requires that a thorough search include a systematic review of sources likely to contain relevant information — including sources that yielded no result. The absence of “voyageur” in Paul’s Quebec records is meaningful only if the search that failed to find it was thorough and documented. This case study documents the systematic review of all Paul Guilbault records in the PRDH database: baptism, marriage, twenty-three children’s records, marriage records for each surviving child. Over thirty individual parish entries were examined. Voyageur does not appear in any document.
