I am a great-great grandson of Elijah & Sarah R. Hall-Pamplin. I descend vis their son William Thomas Pamplin. (brother of Elizabeth) Thus, you are right about Elizabeth's ancestry. I have Elijah's Civil War records and lots of additional ancestry info as well, if you are interested.
I had Elizabith's birth as being in 1853 (per the 1880 census) Is your May 1855 info from a Bible record or tombstone? I would also appreciate dates relative to you, your dad and grandfather. I'm working on a Vol III of Panplin Geneology to follow up on the 2 books that my dad wrote. Also, if you have a picture of Eliz., that would be great. I can scan it and return it, or you could possibly e-mail info to me direct: C_Pamplin@comcast.net
