Hello! I have recently heard that my 6th great grandfather, Hezekiah Hines, born 1754 in Connecticutt was believed to have had Iroquois-Seneca heritage. His parents were Ambrose Hines (born 1726 in Conn. and Sarah Terrill, born 1730 in Conn.) He married Abigail Dolittle. Any information on how I can go about proving his Native heritage will be greatly appreciated. Thanks. Brandi
