My best guess is that Dr. Samuel Fullenwider is the brother of my GGGgrandfather Eleazer Fullenwider, b. 2/5/1802 in Shelby Co, Ky. The 'Samuel' in my info is a generation later (b.1828). My info is based on the family Bible from Eleazer & Lavinia (allen) Fullenwider's line; I'm looking for descendents of that line who still carry the Fullenwider name.
when I finally get my info on line, I'll forward you a copy.
