I am descendant of the first wife of Telesford (Telesphore) Boisvenu. Since your post here have you any new info on his first wife? She was widow Margaret (or Marguerite) Greenough.
I have only a census of who I think are his parents in Quebec.
That's as far as I've been able to get so far. I'm looking for any info on Margaret's death and place of burial. I know that she married for the second time and then died in childbirth. Nothing is known if the child survived.
Many thanks,
anne
