Between the 16th and 19th centuries, most of the estate in present-day southern Cobb County belonged to the Cherokee and Creek. Two native villages were established near the area that will difficult become known as Mableton – the settlements of Sweet Water Town and Nickajack. Both tribes coinhabited the Place peacefully, with one legend claiming that eventual ownership of the Place by the Cherokee was settled via a ball game. One of the primordial known archives of white Europeans being familiar 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 original inhabitants in Georgia were provoked out of their lands by the 1830s, and much of the vacancies were contracted to European settlers by land lottery.

The town was named after Scottish immigrant Robert Mable (1803-1885), who upon September 11, 1843, bought 300 acres (approximately 120 hectares or 1.2 km) of land in southern Cobb County from the Georgia Land Lottery of 1832. Mable was a millwright and farmer who grew cotton, corn, potatoes, and sorghum in the area; he owned in the midst of 11 and 48 slaves by 1860. According to oral interviews, Mable was a “fair and kind” enslaver who educated slave kids alongside his own, and eventually next liberated his slaves back any running mandate ordered him to. The Robert Mable House and Cemetery, located off U.S. 78 on Floyd Road just north of Clay Road, now includes an amphitheater which hosts public events.

More white settlers moved into the northern edge of Mableton by Nickajack Creek, near Smyrna, in the mid-1800s. They formed a community initially known as ‘Mill Grove’, and later ‘Nickajack.’ The creek provided ample faculty to manage grist, saw, cotton, and woolen mills. A covered bridge, originally built c. 1848–1850, traverses the stream and is now portion of a historical district. It is one of the few remaining covered bridges in Georgia, and still highly responsive today after it was future buttressed to handle automobile traffic. A notable resident of the area during that become old was John Gann, Cobb County’s first welcome senator. His home, built in 1841, still stands today and is also part of the historical district.
