I'd like to share with you, the headstone of Mary Ann "Polly" (Hoover) Ingram Sparks....or at least I believe it's hers.
During a previous visit, I dusted this stone with some dirt that was nearby and was able to make out the words "Polly Sparks." The reason I believe this to be my 3g-aunt is that one daughter is buried next to her and another is buried at her feet. Other surrounding graves are Polly's grandchildren. The land the cemetery is located on once belonged to her son-in-law.
Obviously, unless a record of burials for this remote cemetery is discovered, this remains a mystery. Circumstantial evidence strongly suggests it though.
