History

Formed in 1824 from Duval County and Gadsden County

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

Leon County was named after Juan Ponce de León and created by the Florida Territory in 1824. The county experienced multiple boundary adjustments over its history, particularly with Jefferson County beginning in 1827 and with Wakulla County after its creation in 1843.
