I posted a query on the Quebec Research List at Rootsweb and received the information that Marie Blondin's parents, Jacques Blondin and Euphrosine Laplante married June 22, 1840 at Ste. Rose. His parents were Jacques Blondin and Josephte Bigras. Her parents were Andre Laplante and Julie Monet. The source of this information is the Blue Drouin.
Hope this helps. Let me know if you need the next generation back, and I can try to find that, too.
