In the genealogy in the Allaire-Dallaire book #126J
there is no info on their marriage. I have just found it and thought I would share.
In the Baptism, marriage and burials repertoire for the Parish of St Grégoire-de-Naziance, Buckingham,Que.
(county Papineau) 1836-1862, I have found written the following way:
Baptist Allert (Paul & Elizabeth louise Roy) m.to
Christine Damour dite Potvin (Charles & Marie Anne Gauthier) 25-09-1854.
Trusting will be corrected in the book and that it canhelp someone.
