History
Formed in 1843 from Barry County, Dade County and Newton County
An old deed may name a county that no longer exists, or a boundary that has since moved.
Lawrence County was created on February 24, 1843, from Barry, Dade, and an area assigned to both Barry and Newton, but was not fully organized at that time, with parts attached to Barry and Dade for civil and military purposes. It was fully organized and detached from Barry and Dade on February 14, 1845.
