From St-Malo in Bretagne, the son of Pierre-Mathieu and of Anne La Rue took the nickname Bonvivant.
According to Guy Charpentier, a descendant of Pierre Dufour, by his mother
Jacqueline, this soldier would be arrived about 1728: So, " In
April 1729, a battery of the company of Blainville, Vidal Delair said
Lajeunesse, so known as "The Cat", sells window-panes to
Antoine Poudret, baker, then to Mrs. Repentigny. The husband of Mrs
Repentigny, Pierre Le Gardeur, thinks that they are stolen window-panes
to the castle of Callière. He goes to the Guard-House, finds the drummer
and gave him into custody. Mr Repentigny sends the window-panes to the guard of
the stores of the king, Rocbert. This guard requires an investigation of
general lieutenant Raimbault, held at once. The window-panes were well those of
the castle of Callière….
The following day April 13, Delair was examinated and the witnesses assigned. Among them, Marie Catherine Cavelier had received in gift four(4) window-panes from “Dufour, a soldier of the Company of Dubuisson”. When she had heard that its was a robbery of panes, she had immediately given them to Rocbert. Questioned about “Dufour of the Company of Dubuisson”, ...
On April 15, Delair is found guilty and condemned.
On April 28, Pierre Dufour said Bonvivant, soldier 17 year old of the Company of Dubuisson, appears. Pierre Dufour said Bonvivant acknowledges to have taken 4 window-panes in the castle of Callière, which it gave to Marie Catherine Cavelier, woman of Joseph Roy, a baker's assistant. He does not know Delair said Lajeunesse. Pierre Dufour is sent in prison. General lieutenant Raimbault assigns his accomplices Beausoleil and Saint-Pierre, also soldiers, and other witnesses. ...
On June 13, the prosecutor concludes that the addition of informations did not give any reason to change the judgement against Delair and the sentence of April 15 is maintained. Saint-Pierre is untraceable and it receives the same sentence as contumace."
Pierre Dufour will be only admonished and reproved" , because he affirmed to have given 4 window-panes to Marie Catherine Cavalier, which confirmed in her testimony.
