History

Formed in 1872 from Dyer County, Gibson County, Haywood County and Madison County

An old deed may name a county that no longer exists, or a boundary that has since moved.

Crockett County was created on February 19, 1872, from Dyer, Gibson, Haywood, and Madison counties. Over the following decades, the county's boundaries shifted through multiple exchanges and transfers with Gibson, Dyer, and Madison counties to accommodate local residents, with the last recorded change in 1911.

Boundary changes from the Newberry Library, Atlas of Historical County Boundaries; the 5 that matter most are shown first.
