It will be nice to chat someday. I too have moved onto the mystery of Joseph. I have yet to get a good lead other than we know where they were married, where the children were born and have been told he is buried in the Ardoch,Ont area. I have some copies of the children's Bapt certs but do not have one of my Justine. Have you seen it.
I'ld like to send you a copy of the Margerite, Joseph Turcotte marriage cert I have. Just have to see if I too have been looking at the same document at not seeing the words correctly. You can contact me at firstname.lastname@example.org
and I'll send it direct.
I do not have the years accumulated as you, I'm a novice yet at about 15 years, and yes alot of them on the Turcotte and Beauchamp. I have some stuff on Lucy which indicates she may have had Mic Mac ancestry thru the Routhier line. Goes back into early Acadia.
