History

Formed in 1846 from Claiborne County and Hawkins County

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

The Tennessee legislature first authorized creation of Hancock County from Claiborne and Hawkins in 1844, but the chancery court halted organization on constitutional grounds. Hancock was successfully created on January 29, 1846, and the creation was upheld by the Tennessee Supreme Court in September 1848. Over the following decades, Hancock experienced multiple small boundary adjustments with Hawkins County to accommodate local residents, including exchanges, gains, and losses between 1852 and 1881.
