I have an ancestor listed in the Tn. archives as Henry Hugh Long who was sheriff in Perry Co. Tn. 1868-1870. He supposedly served in the 2nd Mounted Infantry Tn. US. Can anyone help me locate his pension file or any other information about his service record. Goodspeed's history of him leaves soemthing to be desired in his miitary service.One of his daughters is my great-grandmother.
