Francis Bennett was born in Coteau Qu. His parents were Francis Bennett and Mary Ann Rousseau. Francis was born in 1790, I am assuming the marriage would have taken place before that. Would there be any records dating back that far?
Francis was much older than Catherine Trombley. I found them in a census for Brasher NY. It shows that he is 33 years older than her! But according to your research he had a previous wife. He was long-lived, he died in 1901 at the age of 111. What a feat! I appreciate any info you can send my way. Genealogy is just so interesting!
