Adele Mcsween is born january 10th, 1855, Les cèdres,Quebec. She's the daughter of Francois-Xavier McSween and Emilie Desrochers (Antoine and Anne Mainville). Frances is her sister. I don't know about J-B. Duquet but he's not related to me; It's another family.
Here's the rest of the genealogy:
Francois-Xavier and Emilie Desrochers: married sept. 13th, 1842 in St-Timothe, Quebec. They had 10 children and then move to the States around 1865. In 1881, Francois-Xavier came back in Quebec. (I'm interested about the children they had in the states if you know anything about that.)
Francois-Xavier(born sept. 5th, 1819, Les cèdres, Qc.) He is the son of Jacques and Marie Girard (Charles and Marguerite Garry)
Jacques and Marie Girard: married nov. 1st, 1801, Notre-Dame de Montreal.
Jacques(born june 11th,1775 in Berthier, Quebec) He is the son of John McSwain and Marie-Louise Maurice (unknown parents)
John McSween was a soldier of the Brittish empire that came to fight against France in 1757. He met her wife in 1760 and started to have a family life around 1769. Established in Berthier, Quebec.
