I double checked my records and have no record of his grave. I checked the records located at NCGENWEB for Cumberland Co. NC Genealogy, an index of graves for Big Rockfish did not have him listed.
You may find help at the Cumberland Co. main library located in downtown Fayetteville. They have a room full of books and records on mico film. They have a complete collection of the Fayetteville Observer on file, with some luck you may find his death listed.
