The dividing line between Tatnall and Montgomery ran from the mouth of Limestone Creek on the Oconee River, just below modern Mount Vernon, Georgia, to the mouth of Wolf Creek on the Canoochee River below Metter, Georgia.

[4] Pendleton Creek (in modern Treutlen and Toombs counties) was used as the border between Montgomery and Emanuel.

The new line differed in the upstream portion of the Little Ocmulgee River and better defined the line and gave Montgomery a small border with Pulaski County, Georgia and Telfair County some land on the northeast side of the Little Ocmulgee River.

The pine barrens and soil quality outside of the river lands made the area unsuitable for slave-heavy cotton producing plantation culture.

Montgomery's status as a majority white county led the region developing different attitudes about secession from other areas of Georgia.

In addition, McRae and Latimer were among the 6 delegates who voiced their protest by against the Ordinance of Secession in the published document.

On August 21, 1917, Montgomery lost additional territory during the creation of Treutlen County, Georgia.
