Thanks Lisa, I appreciate your reply. Since I posted this message I have been in contact with a Hollingsworth researcher who was kind enough to take a photo of her headstone and send it to me. He also found where Amanda's husband, Bryant Dupree, and some of their children are buried, which is Elzey Chapel Cemetery in Union Co., FL. I have since found out that Bryant had remarried after Amanda's death, so that would explain why Bryant and Amanda are buried in separate cemeteries.
I live within a few dozen miles of both cemeteries and hope to make it out there soon. Thanks again. Your reply is greatly appreciated.
