The woman three families share, and none of them knew

An origin no one has found yet

Mathurine Desbordes was born about 1633. She was a fille à marier — one of the roughly 260 unmarried women recruited privately to New France between 1634 and 1662, before the Crown began funding female emigration, and a different wave entirely from the better-known filles du roi who came after. Her parents' names and the parish that raised her are unknown even to Peter Gagné, whose published account of the filles à marier is the fullest record of her life this project has. She appears first as an adult, about to marry, in the Aunis countryside outside La Rochelle — and from there, for the next forty years, she is remarkably well documented for a woman this far back in the family's paper trail.

Three marriages, one crossing between them

About 1655, at Aumalles — the parish of Saint-Étienne de Marans, in the diocese of La Rochelle — Mathurine married Pierre Guiberge. They had at least two daughters, Jeanne and Marie. On 5 May 1659, at La Rochelle, the family enlisted for Canada, acknowledging a debt of 225 livres to Jeanne Mance herself for their passage. Pierre and the younger daughter, Marie, never made the crossing; Gagné reads this as death before departure, or during the voyage itself. Mathurine and Jeanne arrived at Montréal on 29 September 1659, aboard the Saint-André, a widow and a mother of one, already twenty-six years old and starting over on a different continent.

Less than a year later, on 3 May 1660, she married again, to Pierre Bissonnet, a miller from Poitou. A son, Jacques, was baptized the following spring. Then, in 1663, the marriage collapsed: Bissonnet was a bigamist, with a wife, Marie Allaire, still living in Poitou — a fact he admitted outright, along with a claim that he had left her because she was "a witch." Mathurine petitioned Father Gabriel Souart, Bishop Laval's delegate in Montréal, on 1 August 1663. Three witnesses corroborated Bissonnet's own admission, and within days her marriage was annulled, with Laval's own permission recorded for her to remarry whomever she chose.

Her daughter marries a soldier, and Mathurine is in the room

On 23 July 1669, at Notre-Dame de Montréal, Jeanne Guiberge — the child who had crossed on the Saint-André with her mother ten years earlier — married Pierre Cabazier. The act names her as “fille de feu Pierre Guiberge et de Mathurine des Bordes”, which puts her father firmly in the past tense, and then, in the witness list, puts her mother in the church: “Mathurine des Bordes, mère de ladite.” Beside her stands “Michel Bouvier, beau-père de ladite” — her third husband, standing as the stepfather of the bride.

The three of them — bride, mother, stepfather — all declared they could not sign. The groom could, and did.

That groom turns out to be someone. Pierre Cabazier was a soldier of the Carignan-Salières regiment, one of the twelve hundred men sent to New France in 1665 — his name, his bride’s name, and the date and parish of this wedding all appear together in the published regimental répertoire. Two serving soldiers witnessed the marriage, one of them recorded as “soldat de la compagnie de Monsieur de La Motte”, La Motte being a company of that same regiment. Four years after the crossing, the regiment was still in the room.

He came from the parish of La Daurade at Toulouse, son of a huissier royal of that city — and thirty-six years later, at his own daughter’s wedding, he is himself recorded as huissier royal de cette juridiction: a royal bailiff of the Montréal courts. Of the soldiers this research has turned up, he is the only one who ended inside the colonial administration rather than on a farm, and it reads as the family trade rather than advancement in the colony.

The contrast at that second wedding is stark. When Suzanne Cabazier married Charles Rainville in 1705, the witnesses were a merchant and three écuyers — Jacques Le Ber sieur de Senneville, Jean-Baptiste d’Ailleboust, Alexandre Le Neuf sieur de Beaubassin — and their signatures are on the page. Two generations from a woman who could not write her own name at her daughter’s wedding.

One further turn, and it is not a comfortable one. Jacques Le Ber, Sieur de Senneville, signing as a witness in 1705, is the same man for whom Michel Bouvier died two years earlier — the fall from scaffolding at Lachine, building Le Ber’s house. Mathurine’s third husband was killed on that man’s job, and that man put his name in the register at her granddaughter’s wedding.

She did, almost immediately. On 16 August 1663, two weeks after the annulment, Mathurine married a third time, to Michel dit Mathieu Bouvier, a master mason from Anjou who had already crossed once with the Grande Recrue of 1653, gone home, and come back. They had four children: Suzanne, Urbain, a son named Jean, and a second son also named Jean, who died within a week of his baptism. Michel is recorded as an architect in the 1681 census. Mathurine died at the Montréal hospital on 22 October 1698; Michel outlived her by five years, dying at Lachine after a fall from scaffolding while building a house for Jacques LeBer, Sieur de Senneville.

Two daughters, two marriages, three destinations

A son from the annulled second marriage, Jacques Bissonnet, carries neither line this project follows and is otherwise unconnected to it. But a daughter from the first marriage, and a daughter from the third, each anchor a descent this site already tells:

Joseph Philorum Oligny married Marie-Anna Saurette in 1912. After their divorce, she remarried — to Gideon Rock, a man the record now shows was also her cousin, one generation closer to Mathurine Desbordes than Joseph was. Neither man could have known any of this. The three of them meet only on paper, and only because Mathurine Desbordes crossed the Atlantic once, buried a marriage without ever having fully begun it, survived a second, and started a third at thirty years old with nothing behind her but a debt to Jeanne Mance and two dead relations.

The shape of it

Read left to right, this is three separate lines of descent running roughly two hundred and fifty years apiece. Read top to bottom, it's one woman's three marriages fanning out into three families. What makes it worth drawing rather than just listing is the bottom of it: the three lines don't simply end side by side. They close back into each other, and then into one person. Marie-Anna married the man at the left, and then, after their divorce, married the man at the right — and their son Roland, who took his stepfather's surname in 1937, carries Mathurine Desbordes's blood down two of those three paths at once, inside a household that held all three.

Named waypoints only — the elided generations are all carried in full, with dates and parishes, in the three lists below. One further parallel the diagram happens to expose: on every one of the three branches, the surname that ends the line arrives by a woman marrying into it, within a span of fifty years — Roch in 1840, Oligny in 1848, Saurette in 1887.

To Joseph Philorum Oligny — through Jeanne Guiberge

Common Ancestors §5(ii) and the set-intersection re-run of 29 Aug 2026 · nine generations, every marriage and the one baptism between them sighted on an original act · graded Proven end to end — and note which husband this branch runs from. Joseph descends from Desbordes through Pierre Guiberge; Marie-Anna descends from her through Michel Bouvier. The two of them therefore share Mathurine Desbordes alone, not an ancestral couple, which makes them half eighth cousins rather than eighth cousins outright. The generation counts are unaffected; the kinship is real; it is simply half as thick as a shared couple would make it. The Gideon branch below is a different case — it and Marie-Anna's both descend through Suzanne Bouvier and Louis Brien, so that relationship is a whole one

To Marie-Anna Saurette — through Suzanne Bouvier

To Gideon Rock — through the same Suzanne Bouvier

Common Ancestors §5(ii) · Register 01 §3.30a(iii)/§3.30d · eight generations, Mathurine Desbordes to Gideon Joseph Rock, every joint sighted on an original act — one generation closer than Marie-Anna's own line, which is why the two of them are seventh cousins once removed rather than eighth cousins straight · the final joint closed by Gideon Joseph's own Holyoke birth registration, naming his father a barber named Gideon and his mother Oralie (Racicot) — matching Gideon Sr. and Aurélie Racicot exactly

Mathurine Desbordes never met Joseph Philorum Oligny, Marie-Anna Saurette, or Gideon Rock — she was two hundred years and an ocean away from all three of them. But she is the reason two of them could marry each other twice over without knowing it, and the reason the man Marie-Anna married after Joseph was, on the record, family too. A woman with no known parents and no known birthplace turns out to be the best-documented common thread this project has found — not despite the bigamy and the annulment and the daughter who never survived the crossing, but because of how thoroughly one act, one petition, and one register after another kept writing her down.
