hi. not sure if you're still looking for information on the Séguin family. my great grandmother was Lucrece Séguin sister of Armantine. Armantine was married to William (Bill) Picard; I have a picture of them 2 together. They may have had a daughter Cecile (Beauvais); picture of Bill w/ little girl named Cecile. Armentine's parents were Napolean Séguin (dob April or July 15, 1851) and Césarine Gatien (dob Dec. 28, 1872); they married May 3rd 1892 in Casselman, ON.
Lucrese Séguin (Armantine's sister) married William Charette October 26, 1914 in Moose Creek, ON; they were my grand mother's parents. I have not been very lucky finding info on William Charette. If you need more info, maybe I can help. The pictures I've mentioned are on a vhs tape.
Would your husband know/remember anything about William Charette?
