Per Biographical Annals of Franklin County (entry for granddaughter-in-law Ann Fletcher Duffield): "...one of the pioneers of the West Conococheague, a soldier in Col. Bouquet's Expedition, a member of the Pennsylvania Convention of 1776, and a member of the Assembly 1776-77."
Have seen some conflicting information from DAR lineages that he was born in Bucks County, PA.
