All three are by the groom in an English marriage certificate. #1 from 1751 lists him as a bachelor; #2 from 1758 lists him as a widower; #3 from 1763 does not specify a marital status. All are from Kent. #1 and #2 are from the same parish. #3 is from a different parish but not far.
We are trying to determine whether the same person was married more than once for the purpose of constructing a family tree.
