My information shows that William b. 1742/43 was the first son of the Rev. John Gerrard and Mehetable Haughn.The 2nd William b. 29 Aug. 1786 to the Rev. John Gerrard and Mary Gray.I can only add to the confusion, because my information shows his wives as 1) Nancy?; 2) Elizabeth Ann Ayres and 3) Sarah A. Allen.I hope, by now, you have found out something more concrete.
Do you have any information on where Rev. Gerrard came from?I cannot find anything other than he moved to (what is currently called) Gerrardstown, WV.I am a descendent through his first son William and Lucretia Ozburn; their son Jonathan and Eleanor (?); their son Caleb and ELizabrh Pultz; their son John Quincy Adams and Susanna Hurst; their son Isaac Newton and Nancy Rebecca Maxwell and (finally) their son James William and Laura Cross.
