Francois Lamothe dit Cochon (1718-1764) was in fact buried in St-Antoine-de-Tilly as per the parochial register (verso page 9, 1764) deposited with the justice authorities. He is not the son of Jean and MarieAnne Blouard but of Jean and Anne Bruneau. A lot of confusion about the children of these two couples.
Marie Madeleine Cochon dit Lamothe (1776) married Jean-Baptiste Leblanc in St-Jacques de Montcalm on the 14 Jan. 1799.
Francois de Salles Lamothe dit Cochon (1748-1794) married Marie-Josephte Rognon (20 Sept. 1745) daughter of Louis Rognon and Marie-Joseph-Louise Croteau. The actual religious marriage entry is lost, but the marriage contract survived. This information is corroborated from St-Antoine-de-Tilly parochial documents (such as baptisms identifying Louis as the grandfather).
