I believe that Estache Duguay, and Helene Richard are my great-grandparents of Canada. Their daughter Nathalie Duguay, born March 10, 1878-Married 3 times, LeBlanc, Melanson, and Gaudreau. Spelling may be off.
If you have photos of Nathalie that would confirm the relation.
She later moved to Massachuttes.
