In my tree, I have a Moise Joubert married toa Sophie Dauplaise. The couple got married on feb. 16, 1857 in St-François du lac, Qué. The couple had 10 kids according to my database. Here are a few of them: Moise, Joseph, Alphonse, Odilon.... If this is your guy, his parents are Isaac Joubert & Clemence Beauvais. They got married march 02, 1829 in Chambly, Qué.
If you need more info on that family, I could give you a hand. I would like to know more about some of the kids of Moise & Sophie Dauplaise.
