Thank you for your reply. I looked at the writing on the back of the photo again this morning, and find that it is indeed, Thomas WATERS Pettus vs. Thomas WALKER Pettus.
However, I am still looking at a connection here with the Jeffress family. The name "Hudson", "Jordan" and "Ellis" appear prominently in this line. This family ranged throughout the Lunenburg, Charlotte, Nottoway and Amelia county, VA areas, and were planters. I suspect that they are remotely related to your line, but may never find the link. If you are interested in having a scan of this photo, please let me know.
