George was one of seven children of Arthur and Joan Prutt, who were enslaved by Isaac Chauncey (1670-1745) of Hadley, Massachusetts. He was also enslaved by Isaac's son, Richard (1703-1790) of Whately, Massachusetts, and he might have lived for a while with members of the Field family, also of Whately. George, "a pious old slave of Richard Chauncey," was one of the original members of the church. He died at the age of 75, on September 18, 1794.
