This Clinton ABRAMS is also a 3rd great grandson of Henry ABRAMS Sr. of Turkeyfoot, PA. The above mentioned Allen ABRAMS and this Clinton ABRAMS are 3rd cousins, both having the same Gabriel ABRAMS (Fayette Co. PA) as their 2nd great grandfather. You can find all these ABRAMS males listed on WorldConnect, for example.
The other ABRAMS males listed in your message do not clearly fit anywhere into the family tree as I know it. Were you researching the descendents of Gabriel ABRAMS (1750 - 1841, Revolutionary War Vet.) for some reason?
