Between the 16th and 19th centuries, most of the land in present-day southern Cobb County belonged to the Cherokee and Creek. Two indigenous villages were established near the area that will later become known as Mableton - the settlements of Sweet Water Town and Nickajack. Both tribes coinhabited the area peacefully, with one legend claiming that eventual ownership of the area by the Cherokee was settled via a ball game. One of the earliest known records of white Europeans being aware of the inhabitants is an 1839 map depicting a 'Nickajack Creek' converging with the Chattahoochee River south and west of the Standing Peachtree settlement. Ultimately, all native inhabitants in Georgia were forced out of their lands by the 1830s, and much of the vacancies were granted to European settlers by land lottery.
The town was named after Scottish immigrant Robert Mable (1803-1885), who on September 11, 1843, bought 300 acres (approximately 120 hectares or 1.2 km2) of land in southern Cobb County from the Georgia Land Lottery of 1832.
