History

Formed in 1855 from Coffey County

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

Anderson County was created in 1855 from non-county area by Kansas Territory, with Coffey County initially attached to it for civil and military purposes. The county was named after Joseph C. Anderson and became fully organized in 1856, while Coffey County separated from it the following year.

Boundary changes from the Newberry Library, Atlas of Historical County Boundaries.
