I Am Looking for a Couple Graves IN a Cemetary Located Near Manns Choice

I have a couple relatives buried in a cemetery located in Manns Choice area. The names are David Watters who was a civil war veteran and the grave stone according to my father has a notation that he lost a leg in the Gettysburg battle. The other relative is an Edward Smith that is supposed to be buried next to him. There may also be a Cora Watters (Edward Smith's wife) or Cora Smith buried next to Edward also.
