My wife’s grandfather was born in Maine and “adopted” by a Canadian Family in Ottawa. DNA testing by Ancestry.com indicates a significant number of matches from Aroostook County. Family tradition is that his birth surname was “Jeannes” but I can not confirm that. He stated his birth date as January 18, 1890.
Family tradition also states that his parents put him up for “adoption” when they went to India as missionaries.
Are there birth records by date for the County?
