Hello Raymond. Concerning Montebello area, all Patry's family are known as ( Patrice ) they changed name during 1800. Concerning Louis & Philomène Collin, I got two entries in my file who can match with : In St-Sixte (Outaouais area)May/5/1902, Eugène Patry son of Louis & Philomène Gaulin! not very far from Colin maried Eugénie Desrosiers 2. In Angers (Outaouais area)Sept/26/1881 Eleonore Patry daughter of Louis & Phillipine Collin ! samething, maried Moise Leblanc.
During my next visit to S.G.C.F, I will check the microfilm, perhaps, we obtain more information.
If you had more information on your family, I would appreciate to obtain them bécause this information give me more chance to found something on her.
