Harrod, David, and Mary Walcot, Jan. 15, 1700-1701.
David's wife is probably not the Mary Walcott who is the daughter of Jonathan Walcott. See the full discussion on Person:Mary Walcott (2). The children listed on this page largely follow Source:Harwood, Watson H. New England Harwood Genealogy, p. 2: 10-11, but there is not much evidence to confirm this arrangement.
