I am related to Peter Joseph Voisin (1807-1892), the patriarch of the Voisin families of Waterloo County, Ontario, near Kitchener. This was proven by a Y-chromosome DNA match between me and a known descendant of the Kitchener Voisins, Clifton Voisin. I also determined Peter Joseph’s sister Maria Anne Voisin (1798-1879) immigrated to Waterloo county. The next piece of the puzzle was a family connection to Buffalo, New York. That’s where I found a third sibling, Henry Joseph Voisin (1801-?) and his family, in Welland County, Ontario, just across the Niagara River from Buffalo.
