Believe I may be descendant of Elisabetha Waldorff, d/o Engelbertus Waldorff & Gertraud Jungblut. Think Elisabetha married Christian Fritz(b.1724) s/o Johann Christophel Fritz & Agnes Dieterich and had Wilhelm Fritz(b.1760) who married a Catharina Mayer. Their daughter Elsje/Ella Fritz(b.1800) m.Peter John Heiser (b.1790) s/o Johannes Heiser & Margaret Gretzen Rockefeller(b.1760). Haven't been able to determine if Johannes was son of Peter Heiser or brother Jacob Heiser but was grandson of Orgel Heiser & Anna Catherine Haber/Haver and Gt. grandson of 1710 Palatine Johann Peter Heuser & 2nd wife Elizabetha Christmann (widow). Have been searching for more information on the Fritz, Waldorff, Mayer, Blass, Schieffer, Chadwick families.
