Hmm. Birth in 1893 and 1894 means two children born before marriage. Parents Adelard Bienvenu and Anna Robert were married 30-Jul-1894 in Sainte-Cunegonde, Montreal, QC.
I think Marie is Marie Yvonne Desneiges Bienvenu born in 1896 and died in 1897. I have Emma born 1895, but died 1899 (4 years, not 2 years). Jemma is anyone's guess, but if I take a wild guess, I would say she was born in 1897.
