Steve, others have postulated this theory regarding a 1718 date and I have not seen proof one way or the other. According to the work done by Dr. Donald O. Wissinger, thedate of birth is March 6, 1703 at the Parish of Gross-Gerau, near Darmstadt, Hesse, Germany.He is the s/o Johann George Wissinger and Anna Felizitas Runger who had 9 children. Johann's birth date of 1703 fits nicely as their sixth child. And their last was Johann Phillip who was born in 1711 making the 1718 date somewhat unlikely. The data regarding his death at age 60 came from church records which stated he died on April 12, 1779 of a stroke "60 yahre verheated" which means 60 years ????.
