Can you tell me who Elizabeth married/what became of her? What about the other sister?
The reason I ask is because I wonder if your Elizabeth Wells is one in the same as my Louisa Wells changed from Dupuis b around 1838 in NY, because she always listed her mother as born in the US, and I am suspecting that one or both of her parents died when she was young. It appears that her family may have been moving from Canada to NY to Michigan and back alot. I still cannot find her for sure in 1850, even though she married in Ogdensburg, NY Apr 15, 1852.
