George was one of seven children of Arthur and Joan Prutt, who were enslaved by Isaac Chauncey (1670-1745) of Hadley, Massachusetts. (Town records, 1659-1719, Hadley, Massachusetts. See also James Avery Smith, History of the Black Population of Amherst, Massachusetts (Boston, MA: New England Historic and Genealogical Society, 1999), pp. 110-111.) George 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. (James M. Crafts, History of the Town of Whately, Massachusetts, 1899), pp. 168, 256
