Parent-Proof notes for Elizabeth (Spouse 1)
Elizabeth was listed third among his daughters in her father’s will. Meiser listed Elizabeth fifth among the daughters and said she married Mr. Witmer. There was an Elizabeth Witmer age 47 living in Hartley Township with husband Peter in the 1850 Census and that birth year would be just about right, so I have assumed it was indeed Peter’s daughter.
