My grandfather, George Bennett Gagnon (1899-1964), researched our patrilineal history and had the Drouin Institute prepare a Genealogy of the family.
Below are two summary lists he prepared, along with photos of the Gagnon family plaque at Château-Richer during a visit in 1954.
Above: Jean Gagnon, Marguerite Cochon and children.
