Yes, seems so, although I can't find Josephine's death. In Repentigny, which is halfway between L'Assomption and Pointe-aux-Trembles.
PM me with your email addy and I'll send you the cert, will attempt a translation if you like.
I also found a death for Louis Lorion in 1839. Also found the death of Ambroise in 1880, and it's the right guy.
