Hi Mary, I checked Larocque sources. Hormidas married 3 Jan 1929 in Chapeau, Ontario. His parents were not given in the files.
I found the marriage of Joseph Sureau-Blondin married 21 Jul 1902 Ste Anges de Lachine to Marie-Hedwidge Picard. This was from a subscription site which only has Quebec marriages. Their children that married in Quebec: Date Town First name Sex Spouse 1936-08-29 Lachine Marie-Florence-Apolline F Herbert-George Hudson 1938-01-24 Verdun Claire F Jean Bonin 1939-06-03 Lachine Charles M Fernande Desrochers
Notice that Claire married in Verdun. There may have been other children not in the records. Could this be your family? Chris
