I'm currently working on a book of Greene Co., TN cemetery locations. Does anyone have an address or a location for the Robert C. Gray Family Cemetery , on the old Alexander Walker Farm--It had 6 markers. Also, looking for Joseph Horton Grave in the Houston Valley area. And, The Lucinda Huff Grave, that was on the old Gregg Susong Farm, near old Mount Airy School. Thanks for any help. Janice L. Johns-Parton
