I am not sure about your Smiths, but Thomas Smith of Smith Cemetery Lamar Co. is my Smith. I have been trying to locate the Smith Cemetery. It is just listed as, Prospect Rd. It appears to be quite a long rd, and the end of Prospect Road would be the S. Smith Mill Road. I am trying to figure out if it is located near the Mississippi line or further into the state. Can anyone tell me the directions to the cemetery?
