With your help, I was able to find Louise Ducharme and Theophile Bessette's marriage. It took place on December 20, 1852, in St-Joseph's church, Le Corbeau (Coopersville) NY. Théophile Bessette was known as Basset in the USA. I don't know his parents' name. I don't know when he died, but Louise married again, to Joseph Martin (date and place not known. You are right in saying that this Ducharme marriage sttled in NY state.
Now if this marriage the one Gisele was looking for, I don't know, but it could be.
