While I maintain this memorial I do have questions whether he is actually buried here. Wm. was granted 6000 acres of land on the Anna river. Next to his grant was the Harris grant of 6000 acres. The land the cemetery is on was that of the Harris family. It would make more sense that he would be buried on his own land.
William was born in 1638 - sources are the two books ----"Winston of Virgina and Allied Families" and "William Cross of Botetourt Co., VA and His Descendents".
