History

Formed in 1796 from Burke County, Montgomery County, Warren County and Washington County

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

Jefferson County was created from Burke, Montgomery, Warren, and Washington counties. The county was named after Thomas Jefferson. Throughout the 19th century, Jefferson County exchanged several small areas with neighboring counties, including Emanuel and Glascock, often to accommodate private individuals.
