I found this as a note in a gedcom file that I downloaded from somewhere.I'm ashamed to say that I don't remember where I got it.It refers to James Abraham b. 1732 in Radnor Twp., Chester Co., PA and died 1770 in Chester Co., PA.I hope it helps solve your puzzle.
James was Christened in 1732. Stayed single. This was documented from the book " Ancestry of Dr. Thomas Wynne" by Richard Y. Cook, Philadelphia, 1904. (Dwann II, 304, Arch Camb 4 Ser., VIII, 52,53, Arch. Camb., 5 Ser., VIII 258-9. Col Jones MS. pedigree College of Arms.)
