Sargent11 on Family Tree Circles

Looking for family of my paternal grandfather George Sargent, siblings May, Sarah, Henry and Joe. George married to Anne Duran her family originally from Ireland and his Britain. His ancestors, I am told, began in U.S. with a member of British Army in the Revolutionary War eventually settled in Canada after marrying my great(? # of greats required) grandmother a member of the Blackfoot Tribe. My paternal grandparents had 3 children George Joseph, Barbara and Robert Henry Sargent. My father George served in Army Air Corps in Europe flying gliders and C-47s carrying paratroopers, supplies and wounded. My Uncle Robert Henry served in the Phillipines in WWII and my Aunt Barbara died in childbirth in Woburn Massachusetts where they lived. I know so little of them. Help is appreciated.
