I am not sure how Obadiah Wilson's wife would be related to Benjamin and Elias Pegg. Do you know the first name of Obadiah's wife?Benjamin's father's name was Elias and he had a brother named Elias.Benjamin also had a cousin named Elias Pegg, who was born abt. 1759.I think it is this Elias who fought in the War for PA with Capt. Finley's Company and he ultimately settled in OH as did Benjamin.This Elias, b. abt 1759 was the son of Daniel Pegg III and Elias' brother, Daniel IV, had a dt. named Nancy who married a Thomas Wilson.I don't have his background so I don't know if he was related to your Obadiah.
The Peggs were originally Quakers as were some of the Wilsons so there are quite a few Wilsons in my Pegg file.Please send any other information you have on Obadiah or his wife.You can e-mail me directly at firstname.lastname@example.org
