Here is the info I have on my Grandmother and her family. Does this fit with any of your background?
Amedia and Peter Latoille (Latoy) had four children (Lataille seems to be the correct spelling based upon Olive’s Social Security application)
1. Louise Desrocher (D) (half sister)
2. Josephine (D) (half sister)
3. Florence (D)
4. Olive (D-1974 @age 80)
5. Mary (D) (half sister)
6. Amedia (Mid) (D) (half sister)
7. Note: All sons of Amedia died at birth or within a few months
