Calling on anyone with expertise in Acadian records for a particularly tricky connection. One of my children's ancestors (mother's side) is Joseph Mercure who was born in Madawaska and who moved to Baie-Ste-Anne, Northumerberland County. I'm trying to find a way to prove his parents. I have listed likely candidates on Joseph's profile. Those may be red herrings but they seem the two most likely with that surname in Madawaska.
