Dolor Davis (ca. 1593-1673) immigrated about 1634 from England to eventually settle at Barnstable, Massachusetts. Thomas Bancroft (ca. 1622-1691) immigrated before 1647 from England to Dedham, Massachusetts, and later moved to Reading (now Wakefield), Massachusetts. John Davis (b.1787) was a descendant of Dolor in the sixth generation and his wife, Eliza (Bancroft) Davis, was a descendant of Thomas in the sixth generation.
