Throughout the 1920s, the population of Appling County increased as the county was included in land lotteries by the Georgia General Assembly in 1820, 1821, 1827, and 1832. Large proportions of settlers at this time included South Carolinians and others fromTattnall County, Georgia.[4]
On December15, 1824,Ware County was formed by the Georgia General Assembly from roughly the southern half of Appling land districts 4, 5, and 6, and all of land districts 7, 8, 9, 10, 11, 12, and 13. On December24, 1825, Appling County land district 6 was added toTelfair County by an act of the Georgia General Assembly.[5] This created an ambiguity of the border between Telfair County and Ware County that was later solved by additional legislation.
On December8, 1828,Holmesville, Georgia was declared the county seat by the General Assembly,[6] following over ten years of disagreement by local judges.[4] Previously, court was held at residence of William Carter Jr. In 1836, the General Assembly appointed a seven-member commission to find a location for a more centrally located county seat than Holmesville, but were not able to come to a conclusion. The need for a more central county seat would remain a point of contention in county politics for several decades.
On December18, 1857, the part of Appling County that was south of Lightsey's Ford on Big Creek downstream to theLittle Satilla River was taken from Appling County for the creation ofPierce County.[7]
On August27, 1872, eastern sections of Appling land districts 3 and 4 were added toWayne County.[8] This area included Wayne County's current county seatJesup, Georgia, which became the new county seat of Wayne County in 1873. Also in August 1872, the General Assembly called for an election in Appling County to vote on the removal of the county seat to a point along theMacon and Brunswick Railroad. The residents voted for removal and the town ofBaxley, Georgia was selected as the new county seat after the election. In February 1873, the General Assembly mistakenly passed a law giving county commissioners to sell the public lands in Holmesville so that the proceeds can go to the construction of a new courthouse in Holmesville. It amended the law a year later for the new courthouse location to read Baxley, as had originally been intended.
On August18, 1905,Jeff Davis County was created from western portions of Appling County and eastern portionsCoffee County.[9] On July27, 1914,Bacon County was created from parts of Appling County, Pierce County, and Ware County. The remaining section of Appling County that had been located south ofLittle Satilla River became part of Bacon County.[10]
