Smith county had several changes in its boundaries: "Since its organization in 1799, seven other counties were organized from land that was originally part of Smith County. These counties are Jackson (1801), White (1806), Warren (1807), Cannon (1836), Macon (1842), Putnam (1854), and Trousdale (1870)." http://www.smithcountychamber.org/area_historysmithco.htm It's possible your Craighead's would show up on one of the other county census records.
