Jones County, along with Morgan County, Putnam County, and Old Randolph, were established by an act of the Georgia General Assembly on December 10, 1807, from land that had originally been part Baldwin County in 1803 and, earlier, part of the Creek Nation. Jones County was originally bounded by a line running north 56° east to Commissioners Creek, then north 15° west to Cedar Creek, then up the creek to corner Randolph County and Putnam County, then along a line to Ocmulgee River, then down the river to where the old county line between Wilkinson County and Baldwin County was. It excluded parts of what is now Bibb County east of the Ocmulgee River, including the location of Fort Benjamin Hawkins, as they were part of a reserve guaranteed to the Creek Nation. Those areas were later added to Jones County after the Treaty of Indian Springs.
During the initial months of the county’s existence, a town known as Albany served as the county seat. The town was renamed Clinton and was established as the county seat by the Georgia General Assembly on December 22, 1808. Clinton was incorporated as in 1816. During the 1800s Clinton grew as a center of commerce and the cotton trade. Clinton remained one of the most populous cities in Georgia in the mid-1800s.
In December 1810 Jones County gained a portion of Putnam County between Cedar Creek and their original border. In December 1822 Bibb County was established and Jones County lost some of its land to that county.
During the early 19th century, Jones County had a rapid population increase. The peak came around 1835, when the county ranked third or fourth among all of the state’s counties in agricultural wealth. After 1835, soil erosion and lack of funds to develop property drove many farmers to newly opened land elsewhere in Georgia.
Before the American Civil War, a few factories sprang up in the county, including a cotton gin factory at Griswoldville in the southern portion of the county and a woolen factory at Wallace. Griswoldville was founded by Samuel Griswold in the 1850s. During the Civil War, the cotton gin factory was reformatted so it could produce pistols and other weapons for the Confederate Army. Griswoldville was located on the railway linking Macon to Savannah, and became a prime target in 1864 as the Union Army moved through Georgia. On November 20, 1864, the town and the factories in it were burned as part of Sherman’s March to the Sea. Days later the Battle of Griswoldville took place in the area. The town of Griswoldville was not rebuilt.
Many other areas in Jones County were damaged by the Union Army during that time period. The Jarrell Plantation State Historic Site in Jones County showcases one of the few and well-preserved antebellum plantations in Georgia.
In the 1890s a railroad line owned by the Central of Georgia Railway named the Macon & Northern Railroad was built through the county and bypassed Clinton by a mile after citizens wanted the line to not pass through the town. By the early 1900s the population had shifted northeastward and the city of Gray was established. On June 27, 1905, the citizens of Jones County voted on the issues of moving the county seat from Clinton to Gray. The results were 1,289 votes in favor of moving the county seat to Gray and 51 votes for keeping the county seat at Clinton. On August 9, 1905, Gray became the new county seat of Jones County.
Father and son Alonzo and James D. Green were innocent African-Americans lynched near Round Oak and Wayside, Jones County in retaliation for the murder of popular white farmer Silas Hardin Turner on July 4, 1915. A third man, William Bostick, was also lynched on this day. None of those killed received a trial.
