Swain GraveFrom Henderson, take East Main Street to FM 840 and turn right (southeast). Go about 4 miles and turn left (east) onto FM 2867. Go less than 2 miles to the Roquemore Baptist Church. I don't have an exact location for the grave.
This site contained a headstone for
SWAIN, Nancy M [Nelson] 09/07/1823 - 09/16/1889
but the stone is now missing.
There is more information in the USGW Archives.
