Here is all I know.I am researching Joseph Ducharme born 22 Aug 1835 in I belive Ste-Elisabeth de Joliette, Quebed, Canada. His parents were Peter (Pierre) & Mary (Marie) Ducharme. In researching Joseph's wife Melinda Anne Ransom, I find a note that Joseph's mother's maiden name was LaRock, of Montreal Canada. I don't know where to look any more. Thanks for any help you can give me.
