I did some research and found a new information.
We can see on Census 1861-1871-1881 Verchères-Varennes, Pélagie Beauchemin was living with her brother Charles Beauchemin and his family.
On the Census 1881, there is a note for Pélagie Beauchemin: separeted from her husband.
On the other hand, on the marriage record it is mentionned that Pierre was a widower....
I must say that I also thought it was impossible at that time, for Pierre to be married to Adèle, with Pélagie alive!!!
I'll keep looking for more info.
