Well let's see, first marriage to Amable Plante, I see 11 kids, 5 died young, only find 2 marriages for them in this province.
By the way, the name is written St-Onge or Saint-Onge, not St. Onge. French names cousin.
Next marriage with Archange Charbonneau, 3 children, 1 died young 1 married.
Third marriage, 1 baptism then nothing.
Lots of Last Name at Birth corrections needed my friend.
