The Survivor

Hilaire Guilbault of Verchères — From Death Rapids to French Prairie, 1838–1849
He survived the most catastrophic accident on the Columbia River brigades. He gave sworn testimony in a murder plot investigation before James Douglas himself. Six months later he stood as godfather at Saint Paul Mission, binding his family to his cousin’s. Three records — a bateau disaster, a deposition, a baptism — tell the life of a man who came west in 1838 and did not go home.

PRDH Individual #2462814 — Hilaire Guilbault, baptized June 23, 1818, Verchères, son of Joseph Guilbault and Rosalie Marie Lescault Lesot

The Challenge

His Quebec record is clear and his family well-documented. His HBC career is not. No contract survives. The most dramatic event of his service years — surviving the 1838 bateau disaster at the Dalles des Morts — is known only from a secondary annotation. The challenge is tracing a man whose interior years left almost no HBCA paper trail until a single, remarkable document appears: a sworn deposition at Cowlitz Farm in July 1842.

Hilaire Guilbault was born June 23, 1818, in the parish of Verchères (St-François-Xavier), and baptized the same day. His father was Joseph Guilbault, farmer, of St-Paul-de-Lavaltrie; his mother was Rosalie Marie Lescault Lesot. They had married at Verchères on September 23, 1811. PRDH Individual #2462814 confirms the baptism entry; PRDH Family #116841 places Hilaire among his siblings in the Joseph-Rosalie family group. The Quebec record is well-preserved and specific.

The Gauthier document (entry #56) establishes his HBC service as 1838–1848 and notes he is linked to Paul Guilbault. But the HBCA has returned no servant contract for Hilaire. His entry into the fur trade — when, from where, under what terms — is not yet documented in any primary record. For a man whose Oregon life will prove thoroughly documented, his interior HBC years are almost entirely invisible in the archive.

The Family He Left Behind

Hilaire’s father Joseph (b. December 15, 1786, St-Paul-de-Lavaltrie; PRDH #611757) was the son of Paul Guilbault père (b. 1761) — the “Invisible Voyageur” of the companion case study. This makes Joseph the first cousin of Paul Guilbault (b. 1798, “The Canadian”) and makes Hilaire Paul’s first cousin once removed. The Gauthier document’s phrase “linked to Paul Guilbault” describes a relationship confirmed across three interlocking PRDH records.

What the Archive Cannot Yet Answer

No HBC servant contract has been located for Hilaire. The circumstances of his westward departure — which Montreal outfit he joined, what terms he signed, whether he traveled with a specific brigade in 1838 — are not documented in any surviving record identified to date. The Gauthier document states HBC 1838–1848 but provides no supporting citation. The Munnick annotation confirms his presence in the 1838 westward brigade through the Dalles des Morts narrative, but this is a secondary source derived from the register record and brigade history, not from an HBCA contract. The search for his contract in the HBCA Name File and servant record series remains open.

HBCA B.47/z/1 — Deposition of Hilaire Gilbeault, Cowlitz Farm, July 30, 1842, page 1: 'Hilaire Gilbeault, a servant in the employ of the Hudsons Bay Company, stationed at a Farm on the River Cowelitz, deposeth and sayeth...'

The Breakthrough

Two breakthroughs arrive from opposite directions. The Munnick annotation names him as a survivor of the 1838 Dalles des Morts disaster — his dramatic entry into the documentary record of the Columbia District. Then, four years later, he speaks in his own sworn voice in a document no one else could have generated: HBCA B.47/z/1.
1. The Dalles des Morts, 1838
Named survivor of the Columbia River brigade disaster — Munnick Annotation A-34 Secondary Harriet Duncan Munnick’s biographical annotation A-34 states: “Hilaire Guilbault was a middleman in the employ of the Hudson’s Bay Company, and was one of those who saved himself in the bateau disaster at the Dalles des Morts with the brigade bringing Fathers Blanchet and Demers to the West in 1838.” The disaster at Les Dalles des Morts (Death Rapids) on the Columbia River occurred during the HBC Columbia Express, the brigade transporting the first Catholic missionaries to Oregon Country. When a bateau capsized in the turbulent water, twelve people drowned — including Robert Wallace and his wife Maria Simpson (daughter of Governor Sir George Simpson), three children of Pierre Leblanc, and two children of steersman André Chalifoux. Of the approximately twenty-six aboard, fourteen survived. Hilaire Guilbault was one of those who swam to shore.

The Dalles des Morts had earned its name earlier — seven men died of starvation there in 1817 after losing their canoes. The 1838 disaster deepened the rapids’ grim reputation in HBC history. For Hilaire, it was the event that placed him on the Columbia and in the same brigade as Fathers Blanchet and Demers — the priests who would soon begin recording Catholic community life in the Pacific Northwest in the registers that document his marriage, his role as godfather, and his death.

2. HBCA B.47/z/1 — The Deposition, July 30, 1842
Sworn testimony before James Douglas, Cowlitz Farm — the only primary HBCA document in Hilaire’s name Primary HBCA B.47/z/1 (Cowlitz Farm Miscellaneous Items, 1842) contains the sworn deposition of Hilaire Gilbeault, taken at Cowlitz Farm on July 30, 1842, before James Douglas. The document is a single folded sheet in a clear clerical hand, signed by Douglas, with a corroborating note that Narcisse Forceur’s deposition “states to the same effect.” The contents label — in a different hand — reads: “Deposition of Hilaire Gilbeault re intended murder of Charles Forrest.”
HBCA B.47/z/1 — Transcription
Hilaire Gilbeault, a servant in the employ of the Hudsons Bay Company, stationed at a Farm on the River Cowelitz, deposeth and sayeth, that one day, being at work splitting shingles in the woods near the Farm, in company with Narcisse Forcier and Narcisse Moussette two of his fellow-servants who were employed with him at the same job; he heard Narcisse Moussette speaking of the death of the late Mr John McLoughlin, who was murdered in April last, at the Hudsons Bay Company’s Establishment of Stikine, while in charge of that Post, by the Company’s servants attached to it; and that the said Narcisse Moussette went on further to say that if his comrades would agree, he would attempt to repeat the same act here, meaning thereby that he would assist in murdering Mr Forrest the Clerk in charge of the Farm, if the other servants would support him. The said deponent rejected the proposal with horror, and reproved the said Narcisse Moussette for his wicked designs and immediately on his return from work he called upon Mr Forrest, and told him every thing that Narcisse Moussette had said in his presence.

Three things make this document exceptional. First, it is Hilaire’s sworn voice — not a register entry, not a compiled annotation, but his own account of an event he witnessed. Second, it records his moral character under pressure: he rejected the proposal, reproved Moussette, and reported immediately. Third, James Douglas took the oath personally, which signals how seriously the HBC treated this incident. The murder of John McLoughlin Jr. at Fort Stikine in April 1842 — the event Moussette referenced as a model — had shaken the Columbia District. Douglas was not delegating this investigation.

The two men who stood with Hilaire in the woods that day are also named. Narcisse Forcier (also spelled Forceur) filed a corroborating deposition, sworn before Douglas on the same date, that Douglas notes “states to the same effect.” Forcier subsequently appears in French Prairie records as a settler in the same community as Hilaire. Narcisse Moussette, by contrast, does not appear in the Oregon settlement records — his departure from the Cowlitz community after this incident was permanent.

The Kinship the Record Does Not Name

The deposition does not mention Paul Guilbault. But both men were in the Columbia District in July 1842: Hilaire at Cowlitz Farm; Paul, by then a Fort Vancouver boatman settled in the country since 1831, documented in the same Catholic registers where Hilaire would appear within months. They moved in overlapping worlds. The deposition is not the kinship record — B-876 is. But B.47/z/1 is the document that establishes Hilaire as an HBC servant of standing, character, and consequence at the precise moment he was transitioning from company employee to Catholic community member.

M-2 — Marriage of Hilaire Guilbault and Louise, Walla Walla by nation, April 21, 1842, with formal adoption of her four children at the same ceremony. Witnesses: Jean Baptiste Lajoie and Alexandre Pambrun.

The Result

Six months after his deposition, Hilaire stood godfather at Saint Paul Mission. His wife Louise Walla Walla stood godmother beside him. The child they sponsored was his cousin Paul’s son. The Catholic Church Records of the Pacific Northwest document his Oregon life completely: marriage, adoption, godparentage, labor at Cowlitz Farm, land grant, death, and his son buried in the same cemetery where the whole community gathered.
Marriage to Louise Walla Walla — April 21, 1842

M-2 in the Catholic Church Records of the Pacific Northwest (Vancouver Vol. I) records: on April 21, 1842, at Fort Vancouver, Father Demers presided at the marriage of Hilaire Guilbeau and Louise, Walla Walla by nation, aged about 30 years. The ceremony included a dispensation and the formal adoption, by the groom, of four children belonging to the bride. The names of the four children are not given in the register — a noted gap in the Munnick annotation that has not been resolved in any subsequent record. Witnesses were Jean Baptiste Lajoie and Alexandre Pambrun, both members of the established French Prairie community.

The deposition is dated July 30, 1842 — three months after the marriage. Hilaire was already a married HBC servant, a new stepfather to four children, and a resident of Cowlitz Farm when he walked into the woods to split shingles that day.

Godfather at Saint Paul Mission — January 29, 1843

B-876 is the record that makes the Gauthier phrase “linked to Paul Guilbault” legible as human history. On January 29, 1843, Father J.B.Z. Bolduc baptized François, legitimate child of Paul Guilbeau and Catherine, Walawala by nation. Godfather: Hilaire Guilbeau. Godmother: Louise Walawala by nation. Neither godparent could sign; both declared not knowing how to write.

This is the only record that places Hilaire and Paul in the same physical space at the same moment. Hilaire named the child. Louise — who had been Walla Walla herself before her marriage to Hilaire — stood godmother for a child born of another Walla Walla woman. The two cousins were bound by godparentage, the formal Catholic bond of spiritual kinship, at the same ceremony where Paul’s son received his name. Nine months earlier, Hilaire had married Louise. Nine months later, Louise stood godmother for Paul’s son. These families were not merely neighbors at French Prairie. They were family, and they had made themselves so deliberately.

Cowlitz Farm, 1847–1848 — The Roberts Journal

The Munnick annotation records: “From 1847 to 1848 he was a laborer at the Cowlitz Farm belonging to the Company. Roberts, manager of the Farm, noted in his journal of September 6, 1847, ‘Carrier pulling down and carters removing Guilbeaus old house to below the hill where it is to be set up again to answer for a stable this winter.’” The Roberts journal entry is one of the few primary sources for this period of Hilaire’s life that names him by action rather than by legal event. He was moving a house. His house was being repurposed as a stable. He was still at Cowlitz, still in HBC employ, five years after the deposition that had named him a man of integrity before James Douglas.

Provisional Land Grant — March 8, 1847

Oregon State Archives records confirm: provisional land grant, Lewis County, Oregon, March 8, 1847, Vol. 4, Pg. 205, Hilaire Guilbeau. He was registered as a property holder in the Oregon provisional government’s land system during the same period he was still employed at Cowlitz Farm. The land grant establishes him as a settler with legal standing in Oregon Territory, not a transient laborer.

What the Record Cannot Resolve

Louise Walla Walla’s four adopted children remain unnamed in every surviving record. The M-2 register entry notes their adoption with the phrase “four children of the bride only, names not given, were recorded and adopted by the groom” — Munnick’s summary of the register entry confirms this gap. No subsequent baptism, burial, or marriage record in the St. Paul Mission registers has yet identified any of the four children by name with a parental reference to Hilaire or Louise. This is a documented open question, not an oversight.

Researcher’s Note

Hilaire Guilbault is the researcher’s second cousin four times removed, through the line: Gabriel Guilbault fils (b. 1791, cultivateur, Oka) → Gabriel Guilbault père (b. 1762, voyageur, NWC) → Gabriel Guilbault (b. 1731) → Joseph Guilbault → Pierre Guilbault. Hilaire descends from the same Gabriel (b. 1731) through his son Paul (b. 1761), then Joseph (b. 1786), then Hilaire (b. 1818). The Catholic Church Records of the Pacific Northwest, consulted in parallel research on the Laurent Quintal and Marie Anne Nipissing case study and on Paul “The Canadian,” named Hilaire in the same registers. His case study emerged from the same research session that completed his cousin’s. They died the same year. Their families are buried in the same cemetery. The research that found one found the other.

Remaining Open Questions

No HBC servant contract has been located for Hilaire in the HBCA Name File or B-series records. His entry into HBC service in 1838 and his post assignments between 1838 and 1842 are not confirmed in any primary HBCA source beyond the deposition itself. The names of Louise Walla Walla’s four children, adopted at the April 1842 ceremony, remain unknown in all surviving records. No burial record for Hilaire has been identified in the St. Paul Mission register beyond the Early Oregonians Database entry citing his death on June 24/26, 1849.
