History

Formed in 1870 from Jackson County and Overton County

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

Clay County was created on December 7, 1870, from Jackson County and Overton County. The county's boundaries shifted through numerous adjustments between 1871 and 1901, with multiple gains and losses of land to and from neighboring counties including Overton, Pickett, and Jackson to accommodate local residents.

Boundary changes from the Newberry Library, Atlas of Historical County Boundaries; the 5 that matter most are shown first.
