History

Formed in 1855 from Cass County and Pierce County

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

Originally created as Greene County in 1855, it was renamed Seward in 1862. In 1865, Seward County was fully organized and York County was attached to it for judicial and revenue purposes until York was fully organized and detached in 1870.

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