I am trying to trace my husband's side of the family. Information that I have been given is that his gr-gr-grandfather was P.A. Gibson b: Jan 31, 1842 and was married to Harriet ? who was born April 12, 1842. I have no information on their parents. The information I do have on them is only what was found on the headstones at the Salem Cemetary in Old Fort, NC. Would appreciate any assistance.
