About Newnan ...
The City of Newnan was incorporated in 1828 and is named for General Daniel Newnan, a North Carolina native, who was a soldier and later became Georgia Secretary of State and a United States Congressman.
The growth and development of Newnan is largely attributed to the close proximity of Atlanta. Coweta County is located about 40 miles southwest of Atlanta on Interstate 85. Newnan has approximately 27,000 residents and encompasses 19 square miles. The city’s population is projected to continue to rapidly grow over the next several years.

About Coweta County ... 
Coweta County was part of the Creek Nation, named for the tribe headed by William McIntosh, Jr. McIntosh was a half-Scot, half-Creek who relinquished lands to the federal government in the 1825 Treaty of Indian Springs. McIntosh was slain by an irate group of fellow Creeks at his home on the Chattahoochee River. Legend has it that McIntosh received gold in exchange for the lands and that the gold was buried and never found.
By the late 20th Century, Coweta County began to experience a tremendous boom in growth, putting it consistently in the top 100 growth counties in the United States. This growth continues today, bringing opportunity and change. The beauty and the rural character of Coweta remain important parts of our heritage, encouraging innovative land use approaches that strive to maintain rural beauty, while allowing controlled development.
