Cobb County was one of the 24 created in 1832 from Cherokee Indian territory. It is named for Judge Thomas W. Cobb, a former U.S. senator. Marietta, the county seat, is named for his wife. In frontier days, the Chattahoochee River, which forms Cobb's southeast boundary, served as a dividing line between Creek and Cherokee Indian territories.
