Lamar County, the county nearest Georgia's geographical center, dates to 1920 when the state legislature partitioned lands from Pike and Monroe coun­ties. The new county was named for Lucius Quintus Cincinnatus Lamar, a Confederate colonel, member of Congress and U.S. secretary of the interior. President Grover Cleveland later honored Lamar by nominating him to the Supreme Court. The coun­ty seat, Barnesville, derives its name from Gideon Barnes who estab­lished a tavern and stagecoach stop there in 1820.
