Hi Debbie. Marguerite's parents are: Joseph Dandurand and Madeleine Chouinard. Jean-Baptiste and Marguerite married September 24, 1804 Assomption, L'Assomtion County, QC. They also give Jean Baptiste parents as: Jean-Baptiste DeNoyer and Ursule Brusseau.
If you need further help going back let me know I have the Marrige records for that and other Counties in Canada
