The Bertault–Banne Trial
How a sixty-three-page criminal file from the Prévôté de Québec — interrogations, confrontations, a death sentence, an appeal — yields the hardest biographical facts we have for Gillette Banne, and why the record must be read with discipline.
The Challenge
In the spring of 1672, Gillette Banne, her husband Jacques Bertault, and their daughter Isabelle were accused of killing Isabelle’s husband, Julien Latouche, at the family farm across the river from Trois-Rivières. The case produced a large, difficult dossier — and the reward for reading it is a biography almost nowhere else recoverable.
This same file is the source for Gillette’s age — the “quarante cinq ans” that corrected a decades-old birth-year error. Reading the trial correctly is therefore the foundation the rest of her documentary biography stands on.
The Breakthrough
The most productive feature of the file is the clerk’s routine. When he records the opening of each interrogation, he captures — incidentally, under oath — exactly the data a genealogist needs.
“…qu’elle se nomme Gillette Banne, aagée de quarante cinq ans Environ, Natifve du bourg d’Argences…”
She names herself Gillette Banne, about forty-five, native of Argences (near Caen).

Two more opening formulas anchor the family. Jacques states he is “âgé de 50 ans environ, natif de Poitou, paroisse des Essarts” Confirmed — a birth year near 1622 and a home parish matching independent sources. Isabelle, examined first on 1 June (fol. 94), gives her age as thirteen; the clerk wrote douze, then corrected it to treize Confirmed.
“…son père lui a fait prendre [Latouche]… sa mère n’y avait pas consenti…”
Isabelle testifies her father forced the marriage; her mother had not consented.

Isabelle’s trial age (13) is her sworn statement. Her marriage age (~12) is a derived figure — marriage date minus inferred birth year — and must be labelled as derived, never quoted as her words.

The Result
The file yields a three-phase arc: a household, a killing, and a public reckoning — each grounded in a dated primary document.
A marriage the mother opposed
- Gillette, ~45, native of Argences; Jacques, ~50, of Poitou
- Isabelle, 13, married the previous August to Latouche
- A union Isabelle testified her father forced and her mother refused
Reconstructed from testimony
- A failed poisoning, then the killing in the barn with a hoe (houe)
- Neighbours as earwitnesses to Latouche’s cries; son Nicolas (~10) nearby
- The plot described in the accuseds’ own reported words
Two courts, one day apart
- 8 June: Prévôté sentences all three to death
- 9 June: Sovereign Council spares Isabelle “ayant esgard à l’aage”
- Execution the same afternoon; goods confiscated; a will noted in the liasse
Her reprieve reads as mercy, but the mechanism is procedural: under the Criminal Ordinance of 1670, a corporal sentence required three judges and the most lenient opinion prevailed, and any sentence heavier than the amende honorable carried an automatic appeal. Her youth gave the appellate court the ground it needed.
Colonial capital convictions were meant to rest on two unimpeachable eyewitnesses. This case had none to the killing — the neighbours were earwitnesses; the only near-eyewitness was a ten-year-old. The conviction rested on the accuseds’ confessions plus circumstantial “proximate indications” — the bloodied barn, the flail. Any retelling that implies eyewitness proof misstates the record.
The biography that began in an interrogation formula closes in a cost ledger — the jailer’s charge for board and lodging, the executioner’s fee for the walk to the scaffold. Read with discipline, even a murder file becomes a life.
