History
Formed in 1827 from Madison County
An old deed may name a county that no longer exists, or a boundary that has since moved.
Hancock County was created from Madison County on January 26, 1827, but was not fully organized at first and remained attached to Madison County for administrative and judicial purposes. The county was fully organized and detached from Madison County on March 1, 1828. Hancock County was named after John Hancock.
