Where does the name Pew come from? If she is Daughter of Henry York and Margaret Lenderman and wife of Matthew Duty?
There is a 1831 marriage of Matthew Duty to Silpha Beard in Davies Co., Indiana
Looking at the timeline of Zylpha Pew the profile makes no sense. She is having children named Duty from 1809 but doesn't marry until 1815??
Also an improbable number of siblings, both suggests sloppy genealogy which should be viewed with suspicion.
