"Martha Hardeman/1837 GA"

Would be interested to know if anyone has seen the memorial marker for David & Martha Johnson, that I have read, is in the Fender Cemetery, Rt. 2 Lakeland, Lanier Co., GA. (David b. ca 1765 SC, d. ca 1838 Leon Co., FL) and (Martha b. 18 Jan. 1776 VA, d. 23 Mar, 1837 FL) Would be interested to know how the marker reads and if it makes mention that Martha is child of Thomas.And if anyone just happens to have Bible records for Thomas Hardeman that shows Martha as daughter I would be ever so indebted.
