My great grandmother Mary Louise York (Pelkey) was born in 1910 in Penobscot and had a twin sister. She was adopted to a couple in New Brunswick, Canada. The sisters were separated. We are unsure of her birth name or birth parents. There is a conflicting report of her being born in 1908, but we are almost positive it's 1910.
How would I go about finding any type of record of her birth parents? She was native-American and her adoptive parents were Caucasian.
If anyone thinks they might have information feel free to contact me!
