I think we've got a match! I am, however, curious...
I've been going through census data and there was a Dina C. Diette (male) b. 1845 in French Canada, married to Mary. They had five children: Adolphus (1874), Louis (1876), Arthur (1884), Frank (1885), and Ernest (1890). By 1910 Dina was widowed, but he was still living with two of his sons - Adolphus and Ernest.
I'm confused now about "Dina Thomas." Where did you get this data, and is it possible that the names are actually brother Adolphus and father Dina?
And yes - I would love more information about this family line and be glad to give you whatever I can.
