My grandmother, Yvonne Revoir was the daughter of Augustus and Ada and sister to your father. She was born in Manitoba, Canada in 1923 and the last thing I can find on here of her is in the 1930's Census where she was listed as living with the family in Michigan at the age of 6. She also said that her mother (Ada) died when she was very young and that her father left her and her younger sister Mona in an orphanage. Mona got adopted and she never saw her again but my grandmother never did get adopted. She did mention at one point after getting to a certain age, I believe late teens she did go live with Marie and her husband, but I'm fuzzy on the details. I would love to share information and stories if possible.
