Have you seen the book, "The Civil War Diary of Martha Abernathy" by Elizabeth Dargan? It was printed by Professional Printing, Inc. Beltsville, MD and has much on your branch of Abernathys, even a picture of William's home in VA. I am not connected to this branch, that I know of. Trying to find parents of John Abernathy, b. 1830 in NC who married Catherine Cook b 1833 NC. Lived in Johnson Co. Arkansas on 1860 Census.
