Just noticed that you did give me info re: SHARPE and his wife & that I checked the QC death INDEX. Well, you've seen the discrepancy re: DOB for Rosilda (not same as your info). That gives you an idea of the info the gov. has since the INDEX is a government file in cooperation with a Genealogical Society. Since the parents of neither is mentioned, I doubt the gov would have it. When it's available, it's listed in the INDEX. I don't have any baptism registries for Montréal, so I can't help you there. Also, the couple may not have been Catholic, or were they? I only have Catholic registries. Sorry I can't help you further.
