Lisa, Some doubt exists as to the surnames of the various wives and I believe that subject has been covered at length in past postings. Your lineage is basically correct in that William Swift married a Joan(e)( Sisson or Bassett), had a son William who married Ruth (Tobey?) and they had about eleven children, one of whom was Dinah and married a Perry. The earlier births for this marriage (William and Ruth) run from 1651 (Hannah)to Jireh (1665)and therefore your date for Dinah of 1672 is feasible since she was apparently the tenth child.Check through the previous mailings on this subject for more information. Ralph S. Swift.
