I'm looking for information on Pelagie Tessier dit LaVigne our information shows she was born at Beauharnois,P.Q, Oct 6, 1819. The daughter of Jean Tessier dit LaVigne and Pelagie LeBeouf. She married Francois Duchene about 1840 having three sons Joseph, William, John. All the sons were born in at St. Clair Michigan.Any information on Pelagie and her parents would be very helpful. We've had no luck tracing any of them .
