Your Peter Alyea appears to be son of Isaac and Annatje Alyea. Peter served in the King's Orange Rangers during the Rev War, and was in New Brunswick after the War. His brother Joseph also served in the KoR, but did not survive the War. Younger brother John settled later in what is now Ontario, Canada. The father Isaac lost land as a Loyalist and was apparently in New York City during the later stages of the Rev War.
