A researcher I have been using in Montreal has determined that the priest made a mistake on this one. He wrote Charretier for Rosalie when it should be Rosalie Robert. In the Chartier family there are a lot of Chartier-dit-Roberts who are descended from Robert Chartier, and these mix-ups happen. Rosalie Robert is the daughter of Jean-Baptiste Robert and Marie Miron (not Biron). And, you need to know that in this case Jean-Baptiste Robert is a Robert-dit-Fache. Most Roberts are dit-Roberts. The most common are the Lafontaine-dit-Robert. In Ste-Scholastique there is also a Leandre Robert, son of Jean-Baptiste Robert and Marie Miron and a Isidore Robert who is also a son of Jean-Baptiste Robert and Marie Miron.
