"Rotating Formation Tennessee County Boundary Maps" (1777-1985) may be viewed for free at the MapofUS.org website. They rely on AniMap 3.0 software.
In 1792 the Southwest Territory (proto-Tennessee) created Jefferson County out of Greene County, and in 1870 Tennessee created Hamblin County from Grainger, Greene, Jefferson, and Hawkins counties. The land on which the lost county of Caswell was located is now most of Jefferson and the southern part of Hamblen counties in Tennessee.
