Hi Bill,
- Pierre (s/o Pierre & ???) married Esther COUVRETTE (d/o Laurent & Josephte ROBERT) on March 1, 1824, in St-Martin, Laval Co. (The information was taken from the marriage directory of St. Martin.)
Unfortunately, Pierre's mother is not listed. The closest I can find is the marriage of a Pierre Leblanc and a Catherine RENAUD, on Sept. 14, 1795, in St-Rose, Laval Co., but to confirm that, you'll need to take a look at the marriage contract of Pierre and Esther.
Good luck with your research!
