In the Pepin family repertories of the Pepin, Lachance & Laforce Families Association, we have: Marie-Josette Pepin married Jacques Robert on August 4, 1807 in St-François-d'Assise parish of Longue-Pointe (on the Island of Montreal.
Marie-Josette (could be also Josephte)was born and baptised on the 24th of December 1786 in La Prairie (La-Nativité-de-la-Sainte-Vierge parish. She was the daughter of Jacques Pepin and Madeleine Martin who married in Montreal Notre-Dame parish)on March 2, 1778.
This is in the lineage of Guillaume Pepin and Jeanne Meschin who married circa 1645 probably in Trois-Rivières. You can contact me for the rest of the lineage if you are interested.
