Dan, I've found the following in the QUÉBEC DEATH INDEX (1926-1996). What isn't listed is because I've not found the info. I'm including all that I've found in each file. 1) Anna CASAVANT, b. 1870-06-19, d. 1936-10-03 in Montréal. Also known as: Anna BELLEFEUILLE; 2) Léon BELLEFEUILLE b. 1864-03-03, d. 1926-01-07 in Montréal. Since there's no further info in this file, I don't know if he's the one you're researching. Since Alphone B+Anna CASAVANT were married in Sacré-Coeur-de-Jésus parish, Mtl., you may presume she was baptized there. At least it's a start. Same for Eugène B.+Clara HUOT, who were married in Immaculée-Conception parish, Mtl. Ditto for Adéline-Esther B+Napoléon DeLANOVEILLE-DENIS who also married in Immaculée-Conception parish, Mt. I've also found Léon LAROCHE (Augustin+Émilie BELLEFEUILLE) m. 1858-02-15 in Notre-Dame parish, Montréal, QC to Adéline CHALIFOUX (Augustin+Madeleine LAMONTAGNE). If this is your relatives, you may wish to search Notre-Dame parish for their DOB's. That's all I could find. Hope it helps you out a bit.
