Re: To all descendants of Rene Beaudin of Niort, France & LaPrairie, Quebec
I wonder where these family lines connect. I believe that Rene's father was Charles (born ca. 1640), whose father was Jean Baudin. Apparently they lived in Niort. Maybe Charles and Pierre were brothers. Charles married Jeanne Moinet on 11 APR 1660.
It's interesting that your Pierre married a Desmarais: My grandfather Arthur Beaudin married Adele Desmarais in Bay City, Michigan.
