Hi Pat, I thought I would butt in here, I have found the info you are looking for in my Dictionaire des Familles Ouellet-te. Alexandre Ouellet (son of Etienne & Catherine Milville-Deschenes) no birthdate listed.
He married Marie-Anne Laplante-Madore on 10 Feb 1806 at Kamouraska, Qc. She was the daughter of Jean & Marie-Anne Ouellet.
There children are as follows; 1) Antoine 2) Francois-Xavier 3) Marie-Vitaline - born 23 Mar 1828 4) Emelie-Locade 5) Deline 6) Marcelline - born 29 May 1829 7) Fabien-William 8) Marie-Francoise 9) Theodore - born 23 Feb 1833 10) Delina 11) Alexandre 12) Georges
Although our lines don't connect until Rene, the immigrant ancestor, I thought I'd try to help. I am descended from Rene's son Gregoire, while you are descended from Mathurin-Rene, I guess that makes us cousins of a sort. Mary
