My initial research shows that the Angelique Boulet who died in 1799 is not the wife of Francois Chabot who married Genevieve Gagnon. THe very location makes it questionnable for the funeral of Francois' wife.
I have not been able to locate the marriage record of Francois and Gagnon but I will keep looking.
Francoise married Pierre Pierre Labrie in 1804. I will check to see if her mother was still alive at the time. Same for ther father.
