Also in that cemetery are:
Joseph E. Morefield 1877-1964 Walter B. Morefield 1905-1984
Rock Springs Methodist Cemetery is near Kingsport, TN in Sullivan Co, but it's close to the Washington Co. line.Jonesborough is several miles away, so it's interesting that he was buried there.I found these stones by accident when we were searching for my husband's mother's relatives.
