History

Formed in 1873 from Upshur County

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

Gregg County was created from Upshur County on May 7, 1873, and fully organized the following month. The county gained land from Rusk County in 1874 but lost land back to Upshur County in 1882 to meet state constitutional requirements for county seat distances.
