About your grandfather, Blaise Kuno Ducharme: was he the one that married Joyce Clark in 1949 (Windsor, ON)? If not, could you give me some details about him?
About Nicolas Charron, born 1589: your information about this link likely comes from T.W. Denomme's book, «Our French-Canadian Ancestry in Huron County".
Mr Denome was a fine genealogist, but this link is uncorrect. If you have interest in Charron-Ducharme family, I suggest you visit our association's website, at http://www.genealogie.org/famille/charronducharme/http://www.genealogie.org/famille/charronducharme/
