My maternal grandmother was a Gamache and my paternal grandmother was a Boucher. I have in my database a Marie-Elizabeth Bazin and Jean-Baptiste Gamache who married 15 Nov 1730 in Cap-Saint-Ignace. They had two children that I knew of:
Joseph Gamache m. Marie-Elisabeth Fournier Nicholas Gamache m. Marie-Claire Caron

Jean-Baptiste's parents were Louis Gamache and Angelique Miville (according to the Blue Drouin) (I know of 4 of their sons)

Louis Gamache's parents were Nicholas Gamache and Achille Cloutier (again according to the Blue Drouin)

I know the Blue Drouin is not always correct but I would love any information you have on the descendents of this line. I do not have a Louis listed as a child of Nicholas Gamache and Elisabeth-Ursule Cloutier so I was a little confused.

My line descends from Nicholas also through his son Pierre but I have been trying to find the descendants of both of these families.

I would love to share information.
