I found this on KEIGHLEY in Fayette Co, PA. Not sure if your line, of course. "This family are of English birth and residence for many generations, the English home being in Yorkshire, where Jeremiah Keighley lived and died in the city of Leeds. He was a wool buyer and a member of the Church of Englad. He married and had sone, also 3 daughters." mention is made of several who emigrated to PA. No Jonathansm tho. Interesting sounding people.
