I have in my database Pierre VINCELETTE m. Agnes DURANLEAU (DESRANLEAU is a dit name for CHATEAUNEUF) on 11 May 1886 at St-Joseph d'Ely, Valcourt, PQ.This was taken from a marriage index so the spelling of Agnes' surname could be different.Could this possibly be your Pierre?
Parents of Pierre were Nicolas VINCELETTE & Julie GERMAIN.I found this couple in the 1871 & 1881 Census in Ely, Shefford Co.From that data I have an approximate birthdate for the son Pierre (also using the first name Cervulo?) abt. 1861.
I have one son (Arthur Edmond) for Pierre & Agnes but I am sure there are more children.
I have lots of information on ancestors and not much on descendants.I'd be glad to share.Richard Le Maire and I exchange data regularly as well.
