History
Formed in 1873 from Greene County and Randolph County
An old deed may name a county that no longer exists, or a boundary that has since moved.
Originally created as Clayton County from Greene and Randolph counties on March 24, 1873, it was renamed Clay on January 1, 1876. The county was named after John M. Clayton and Henry Clay. Clay gained land from Greene County in 1895 and lost land to Randolph County in 1957.
