I have the year of this marriage as 1840. I have that from a Lalibert-Faubert genealogy (FTW) file that I downloaded (I think from www.ancestry.com), so it is not first-hand information, and it may be an estimate based on the birth of Marie in 1842. The source also does not mention the place of marriage. The database says this Jean-Baptiste Faubert was the son of Jean-Baptiste and Susan Peltier (Pelletier?).
I realize this is not much, but wanted to share what I did have.
