(706) 638-1453. Walker County originated in 1833. Drawn from the original Cherokee County and part of Murray County, the region owes its name to Major Freeman Walker of Augusta, a lawyer and U.S. senator. Although residents first called the county seat by its Indian name, Chattooga, they later renamed it to honor the Marquis de Lafayette.
