Great Marsh is like all other older graveyards here in the South, there are no mapped plots. Back in the day when someone died, one of the Trustees would have told the family where to bury and would have told them that they could have 1, 2, 3, etc... burial places in a row at a location pointed out to them. The same is true for old family cemeteries as well.
If I remember correctly, you are perhaps a descendant of a William Baxley? Could you e-mail me that information again, and is there any chance that your William Baxley served in the War Between the States? I believe I have a newspaper clipping where a W. Baxley and M. S. Baxley were wounded in service.
