Ken, I have a copy of the Repertoire des Cadieux d'Amerique which only shows 4 known children for this couple: Joseph, 1746-1751 Marie-Celeste, b. 1748 Jean-Baptiste, 1749-1750 Jean-Marie, 1751-1829, m. Marie-Archange Duceppe(Ducep,Dusep)03Apr1780 Riviere-des-Prairies, St-Joseph. She was dau of Pierre Deceppe & Marie-Genevieve Beauchamps.
Jean & Marie had 4 children.
I also show that Joseph m. 2nd Suzanne Coustance (sometimes shown Argentcourt)13Jan1755 same parish; and the Repertoire list 6 children of that union: Gabriel (1756-1757) Joseph (1761-1761) Joseph (1762-?) m. Josephe Gervaise 24Oct1785 Varennes Marie-Archange (1764-?) Fabien (1765-?) Joseph (?)m. Marie Louise Corbeil 1Feb1802 Riviere-des-Prairies, St-Joseph. One son, also a Joseph.
This last Joseph is listed as a separate person from the 1762 Joseph, but I suppose he may have been the same man working on a second marriage.
