Finding a Gabriel Guilbault in the
North West Company Records

Three Records, One Name, and the Test That Undid Them

A fur trade account book gives you a name and a number. No age, no parish, no father’s name. This is how I found Gabriel Guilbault in the North West Company account books — and how the parish registers of Lower Canada later showed that the man I had found was not the man I thought.

Revised 9 August 2026 — the conclusion of this post has changed

When this post first went up, it presented three account book records as documenting Gabriel Guilbault père’s return to the fur trade in his fifties. That identification has been withdrawn. The parish registers place him in Lower Canada during the account’s Athabasca year, and several figures reported here were wrong from the plate.

The search method is unchanged and still works — it is the most useful part of this post, and it is why the post stays up. What has changed is what the search proved. Corrections are marked in place rather than quietly removed.

When I searched the North West Company Account Books Name Index for “guilb,” I wasn’t sure what I’d find. Gabriel Guilbault père had married Marie Josephte Abitakijikokwe at Oka in 1801, legitimating children born during their years together in the pays d’en haut. A baptism of 1798 called him voyageur et maintenant agriculteur. So when the index returned his name in three volumes, the conclusion seemed to write itself. Testing it properly took another two years, and produced a different answer.

North West Company Account Books Name Index search results for the Guilbault surname cluster

The North West Company Account Books Name Index (1795–1827) at the Archives of Manitoba. A search for “guilb” returns seven entries from 3,791 — a Gabriel in three volumes and a Paul in two. Note the dates against each entry: they describe the volume or the index record, not the man’s service. That distinction turns out to matter a great deal.

What the Index Returns

Three records, three document types, three spellings — Guilbault, Guilbeau, Gilbian. French-Canadian names were rendered phonetically by whichever clerk held the pen, and no two agree. That much is ordinary.

What is not ordinary, and what took two years to see, is the first column. Those are index dates. They describe the volume, or the entry in the finding aid. They are not statements about when the man worked — and the 1816 against folio 414 is the reason this post originally described a five-year career that the account itself does not show.

The Actual Records

What each plate says when you read it rather than the index
F.4/29 • Lac La Pluie Blotter 1820

Record 1: A Day’s Purchases at Rainy Lake

Reference: F.4/29, reference 35

Document type: A blotter — a daily rough ledger recording transactions as they happened at one post.

Index leaf to the Lac La Pluie blotter, 1820
Index to the Lac La Pluie blotter, 1820: the G run reads Gbault Paul 33 · Gigains Ignace 34 · Grandbois Michel 34 · Gayazon Pierre 35 · Guilbault Gabriel 35 · Goulait Jacque 36. Gayazon and Guilbault share reference 35, so “two entries apart” describes a sequence in an index rather than a position on a page. A Gabriel and a Paul of this surname both held accounts at this post in this season. Which Gabriel, and which Paul, the volume does not say.
Purchase run of Gabriel Guilbault at Lac La Pluie, 26 July 1820
F.4/29, reference 35: a single dated purchase run, 26 July 1820, footing at 133. Cloth capot 40 · common cotton shirt 12 · half-pound soap 6 · cold thread 4 · horn comb 1 · six needles and six flints 2.10 · one and a half yards fine calico 24 · large black silk handkerchief 12 · one portage sling 6 · trunk and three cords 6 · two pints rum 20. Below the rule, in a second hand: “Paid him 30 promised by [A. G.] McTavish” and two equivalent pints on 28 July.
Correction
This leaf carries no balance, and no Athabasca notation

The earlier version of this post captioned this image as an account closing at 188 livres with a transfer notation reading “To Atha—.” Read at full resolution, it carries neither. It is a dated outfit purchase footing at 133.

The 188 is real, but it lives on the receiving side — entered in the Athabasca blotter as a debit reading To Sundries at Lac la Pluie — 188. The link between the two posts stands, and stands on a specific non-round figure. It was simply being cited from the wrong book.

About Lac La Pluie: Rainy Lake was a transshipment hub — the meeting point between the Montreal brigades and the interior. Voyageurs and goods passed through in both directions each season.

What the record shows: a man outfitting himself for the interior in late July 1820, on credit, at a post store. The portage sling is the one item on the list that only a working canoeman buys.
F.4/37 • Athabasca General Blotter 1820–1821

Record 2: The Account That Foots

Reference: F.4/37, reference 100

Document type: A general blotter, aggregating accounts across the Athabasca district.

Cover card of HBCA F.4/37
F.4/37 cover: Section F, Class 4, Piece 37 — North West Company account book, 1819–1821.
Index leaf to the Athabasca general blotter, 1821
Index to the Athabasca general blotter, 1821: Gibeault Paul 93 · Gilbian Gabriel 100 · Guilbian Paul 104. The reference 144 given in the earlier version was a transposition. The x-marks denote settled accounts. Note that the clerk renders one family three ways on a single leaf — and that there is exactly one Gabriel in the department, with no second man hiding under another spelling.
Athabasca account of Gabriel Guilbeau, reference 100
F.4/37, reference 100: the entry “To Sundries at Lac la Pluie — 188” carried in as a debit, tying this account to the Rainy Lake leaf. Wages 650. Closes at 336, settled. The earlier version of this post gave the wage as 450 — a figure the page cannot foot to.
How the page foots — F.4/37, ref 100
1820  By Balance (opening credit) ....  42.10
1821  By Wages ......................  650
                                          692.10

      To Sundries at Lac la Pluie ...  188
      To post purchases, net .........  168.10
      To Balance ....................  336
                                          692.10   SETTLED
The page balances at 692.10 both ways. That is what makes the reading secure — and it is why a wage of 450 could not have been right. Purchases include a blanket, leggings and capots at 21.10; a pint of rum at 90 with cotton and other goods at 44; a shirt and corded cotton at 40; a charge of 40 to Lewis Mongan; and three pints of rum at 90.

The 188 — what it proves, and what it doesn’t

A balance of 188 livres carried out of Lac La Pluie and into an Athabasca account is not a round number, not a standard wage, and not a figure that recurs by chance. It ties the two posts to one man, and that link has held through every subsequent correction.

What it does not do is say which man. A cross-reference proves that two records describe the same person. It says nothing about who that person was.

F.4/32 • NWC General Ledger Folio 414

Record 3: The Ledger Account, Read From the Plate

Reference: F.4/32, folio 414. Specially scanned by the Archives of Manitoba, February 2026.

HBCA F.4/32 folio 414, the account of Gabriel Guilbeau
F.4/32, folio 414: headed Dr Gabriel Guilbeau Cr, immediately below the account of Louis Giroux. Five consecutive annual wages — 551, 330, 687.10, 500, 650 — each followed by a balance struck and carried. Closes at 336, matching the Athabasca blotter.
Correction
The account opens in 1817, not 1816

The first line of the folio is a wage credit — To Sundries against By Wages 551 — with no balance brought forward from an earlier folio. The 1816 in the finding aid describes the volume, not the man.

That single distinction retired a five-year career, an age, and a narrative. An index date is a fact about a record; it is never a fact about a life.

What the opening line does establish: the account has no history before 1817. A man long in the trade would normally arrive on a new folio with a balance attached to him. This is someone beginning documented company service — which sits awkwardly with a fifty-five-year-old voyageur of the 1790s and comfortably with a younger man. A lean, not a proof; a clerk opening a new ledger can start a fresh folio for anyone.

One entry worth noting: in the 1819 credit column, By Mr Paul Guilbeau — 50. Two accounts transacting with each other is real evidence of a working relationship between two named men. It does not say which Gabriel, or which Paul.

Analysis
What the settlement means

Whoever held this account ended his NWC service with the company owing him 336 livres, not the other way around. Many fur trade workers finished in debt, caught between goods bought on credit and wages that never quite covered them. This man did not. He walked away with money owed to him and the account marked settled at the 1821 merger.

That is a real finding about a real person. It is simply not yet a finding about a named person.

The Test That Undid It

What the parish registers say about the account’s own wage years

The identification rested on an argument that seemed obvious: Gabriel père was a documented voyageur, and here was a voyageur’s account under his name. To test it, every appearance of his name in the Quebec registers was read for one thing only — whether the act says he was there.

That distinction is the whole of it. A baptism naming a man as father asserts the child’s legitimacy; it is not an observation that he stood in the church. Presence is credited only where the act carries the clause — ainsi que le père présent — or records him acting as a party.

The result
He was in Lower Canada during the account’s Athabasca year

18 June 1819, Rigaud. At the baptism of his son Joseph: lesquels, ainsi que le père présent, ont déclaré ne savoir signer. 23 June 1819, Rigaud. Godfather at another baptism, present again. 20 February 1821, Saint-Eustache. At the baptism of his son Charles, declaring in person.

The account’s closing wage of 650 is the Athabasca year. Athabasca is a wintering department — it cannot be worked seasonally, and the brigades left Lachine in May. A man declaring at Saint-Eustache in February 1821 was not at Fort Chipewyan that winter. The two statements cannot describe one person.

Two wage years, 1817 and 1818, carry no evidence for anyone in either direction. That is the honest residual, and the case study states it as one.

Losing the account does not cost Gabriel père his trade. It is documented, and by better evidence than an account book — three children baptized at Saint-Paul-de-Lavaltrie on 10 October 1798, each entry stating the child was born and privately baptized dans les pays d’en haut. Three interior births across eight years is a hivernant’s record: a wintering voyageur who lived where he worked. His voyageur decade was the 1790s. It was simply never the 1820s.

The Paul Question

One half resolved in the parish registers, one half still open in the ledgers

A second name recurs alongside Gabriel’s in these volumes — Paul Guilbeau, also written Gibault, Gibeault, Guilbian. Two separate questions hide inside it, and only one of them has an answer.

Resolved
Paul père was Gabriel père’s brother

Paul Guilbault was baptized 23 April 1761 at Notre-Dame-de-Montréal, son of Charles Gabriel Guilbault (1731–1784) and Marie Charlotte Morin — the same parents as Gabriel, baptized at L’Assomption the following year. The 1783 Varennes marriage register names Paul “fils de Gabriel Guilbeau et de Charlotte Morin” and places Gabriel Guilbeau as a witness at the wedding: the one Quebec document putting both brothers in one place at one time.

Paul’s own fur trade career is documented by two signed engagements — 19 July 1798 under Rod. McKenzie, and 22 May 1821 under Samuel Black, two months after the company had dissolved. Not one Quebec record ever calls him a voyageur.

Not resolved
There are two men named Paul Guilbault in these volumes

A second Paul Guilbault of this family — born 1798 at Lavaltrie, a first cousin once removed — appears in the same records in the same years. The clerks write Gibeau, Gibault and Guilbeau for both men, so spelling assigns nothing. The wage figures do: Paul père contracted at 500 and settled at 617.14; the Canadian ran at 350 with a balance of 96, and each set matches that man’s own documents elsewhere.

The earlier version of this post gave folio 396 as Paul père’s ledger account. It carries 350 and 96 and belongs to the Canadian. Paul père’s own ledger account is p.389, and it has not yet been read.

Which of the two Pauls held the Lac La Pluie account at reference 33 has never been established either.

Downgraded
“By Lieut Franklin — 100”

Paul père’s Athabasca account carries a credit reading By Lieut Franklin — 100. Franklin’s published Narrative confirms he was at Fort Chipewyan from late March 1820, requisitioning company men and paying through company establishments rather than in cash — the mechanism that produces a credit of exactly this form.

But the two Pauls pull in opposite directions. The credit sits on Paul père’s account at 500. The account whose charges trace the Franklin corridor in order — in from Fort William, then Fort Chipewyan, then Slave Lake, then sundries at Fort Providence, in the season Franklin travelled it — is the other Paul’s at 350. Fort Providence was an ordinary company post as well as the expedition’s rendezvous. The documents do not choose, and the entry is now logged as unresolved rather than probable.

The Geography of a Voyageur’s Life

Where the records place this family, and where they don’t

Four Thousand Miles of Canoe Routes

From the rapids where Gabriel père met Marie Josephte, to the mission at Oka where they married, to the posts named in an account book whose holder is still unidentified.

The route the account describes — whoever held it. Two men of this surname held accounts at Rainy Lake in 1820.
Following the canoe routes
Why the journey to Oka made sense

Sault Ste. Marie sat on the network connecting the interior to Montreal, and voyageurs travelled these routes on a seasonal rhythm — out in spring, home in autumn. The journey from the St. Mary’s Rapids to Oka followed established water: across Lake Huron, up the French River, across Lake Nipissing, down the Ottawa to the Montreal region. Several hundred miles, weeks by canoe, and a route a working voyageur would have known by heart.

Country marriages were recognised within fur trade communities, but Catholic traders often sought a church ceremony to give their families standing in colonial records — legal recognition, inheritance rights, a place in French-Canadian society. The 1801 ceremony at Oka was not unusual. It was part of the rhythm of a life lived between the pays d’en haut and the settlements.

How to Research Your Own Ancestor

The search still works — this is the part of the post that has not changed

Everything below is unaffected by the withdrawal above, and it is the most useful thing on this page. The method found the records. What it could not do on its own was identify the man — which is why there is now a sixth step.

Step by Step

1

Search the NWC name index

Archives of Manitoba → HBCA Resources → Name Indexes → North West Company Account Books, 1795–1827. Search the surname and every spelling variation you can think of, then search the given name alone. The database holds 3,791 entries. Try a partial string — searching gib as well as guilb returned six further entries in this family that a surname search missed.

2

Record the reference codes — and treat the dates as suspect

Note the class marks (F.4/29, F.4/32) and any folio numbers; you need them to order anything. But write the index date down as the index’s date, not your ancestor’s. It describes the volume or the entry. Confirming it against the plate is step three for a reason.

3

Check for digitised records — and check the microfilm structure

Search the Keystone descriptive database on the reference codes. Many volumes are online. Watch for substitution cards: reel 5M6 is catalogued as North West Company account books 1817–1821, but at image 420 it carries a card reading “For F.4/32 see Reels 5M7 & 5M8.” A researcher working 5M6 in order would conclude the ledger had been searched.

4

Request research assistance

For anything not digitised, contact the Archives of Manitoba directly — folio 414 was scanned and sent within days. The Manitoba Genealogical Society and the Archives’ researchers-for-hire list are both good routes.

5

Make the page foot

Before you quote a wage, add the column. An account that balances tells you your reading is right; one that doesn’t tells you something is misread. A wage of 450 was reported here for two years because nobody totalled a page that only closes at 650. Figures, not spellings, are what distinguish men in these books — two men of one name are told apart by their wage column every time.

6

Then go home and test it against the parish registers

An account book gives a name and a number. It gives no age, no parish, no father. If your family recycled given names — and most did — finding the record is the easy half. Build a presence ledger: go through every parish act naming your man and credit presence only where the act says so, in its own words. Then set those dates against the account’s wage years. That is the step that decides it, and it is the step that undid this post.

Why This Research Still Matters

Three account books, a cross-post balance, and a settled account: all of it real, all of it still in the file. What changed is the name attached to it.

That is not a failure of the method. It is the method working — slowly, and against the answer I wanted. Every fur trade family that reused its given names presents this same problem, and the account books alone will never solve it. The parish registers decide, or nothing does.

Are You Connected to the Guilbault Line?

If you descend from the Guilbault (Guilbeau, Guilbeault) family of Charlesbourg and the Quebec parishes, from the children of Marie Josephte Abitakijikokwe, or from the founding families of the line — Senécal, Séguin dit Ladéroute, Morin, Couillaud dit Roquebrune, Gaulin — I’d like to compare notes. Documented trees, DNA matches, family papers, and even half-remembered stories have all moved this research forward.
