To find the ancestors of my great-grandfather Joseph Voisin (1858-1916) in connection with the Ontario patriarch, Peter Joseph Voisin (1807-1892), it helps to research other families in the area that may be related. They can help me “triangulate” in on my direct-line ancestors. With a little detective work, one such family proved to be a surprising discovery.
An early settler in Waterloo County, Ontario was Maria Voisin, and her son August Voisin, who was a tailor. A reference to her and her son is found in a history of the Catholic Church in Waterloo County.1 The reference indicates she was present in or before 1850 and it includes a picture of Madame Voisin herself. I suspected she was related by marriage to Peter Joseph Voisin (1807-1892), and was perhaps his sister-in-law.
