I believe your Robert Abernathy was my4th great grandfather. If so, Jess mentioned in your post is my line. Jess fathered Madison Abernathy and Madison was my grandmothers daddy. My Robert entered a quarter section in Fayette and Union Counties in 1814 at the land office in Cincinnati. Let's compare information. I live within 6 miles of the farm where Robert lived and,as a child was frequently there although it belonged to new people by that time.
