Hi, we have the same great grandfather (9 times also) so therefore are cousins.
Do you know if you are from the Quebec or Manitoba branch or the branch that moved to the U.S.
I do not know where to get the book.I got a copy at the family reunion in 1984 and it was done with TLC by a cousin.I had a reply from a U.S. cousin (Greg Bohemier) who has done a family search, going back to before Pierre was born and his son came to Canada in 1665 I think.He has all the details.(totally amazing).There is apparently a town close to where Pierre was born that is called Boismé which isthe name we originally had (also Boesmé).He is checking to see if it was a family estate (???) and is also trying to get information from Poitiers that apparently takes the family history back to 1084 (or thereabouts).
