Byrd, a little community located about two miles east of St. George on U.S. Highway 78 at its junction with County Highways 161, seems to have been so named for the Byrd family presently or formerly residents there.

Cattle Creek community is located in the extreme northwestern area of the county and is bounded by Cattle Creek (from which it apparently takes its name) on the eastern side and by Orangeburg and Colleton Counties to the northwest and southwest respectively. It is a very fitting name in an agricultural area.
Club House community is located at the junction of County Highways 63 and 84, about two miles equidistant from U.S. Highway 17-A to the north and the Charleston County line to the south. It is said that the Club House burned some years ago. Evidently it was the local gathering place, similar to the old country tavern.

It extends from approximately a mile east of the junction of U.S. Highway 176 and County Highway 20 with Interstate Highway 26, and from near the junction of County Highways 11 and 337 to the Orangeburg County line.

Fitter's Kitchen is a black community located just outside of and to the northeast of St. George, bordered by U.S. Highways 15 and 78. The dialect here is most difficult to understand and seems to have no relationship to the coastal Gullah dialects. It was concluded by the county employees that the name was actually Phillis' Kitchen, evidently a community gathering place in that area.
Four Holes Swamp is the large swamp which forms the upper half of the northern boundary of Dorchester County with Orangeburg and Berkeley Counties. It is said to be so named because the water in the swamp starts from four holes or springs. Derives its name from four large pits which alternately suck in and expel the waters of the swamp. From the discharging holes the water boils over like a mighty well, and into the receiving holes it plunges with considerable noise.

Jedburg was named for its first postmaster, Jed Selicks.
Lincoln Green is a little black community located on both sides of U.S. Highway 78 about a mile west of the town of Dorchester. The dialect here is difficult to understand. The Lincoln part could mean that it was named in honor of their benefactor; the green could come from a pasture or cattle farm.

Old St. George is a small community, located about a mile southwest of the town of St. George. It is bordered to the northeast by Polk Swamp, to the southeast by County Highway 49, and to the northwest by the Cow Tail community. Possibly it cornmemomtes the moving of the location of the County seat (St. George) from the south side to the north side of Polk Swamp.
Old Wire Road is the local name for County Highway 19 as it runs from its junction with County Highway 30 to the Orangeburg County line. This road lies about two miles from the Edisto River, the Dorchester - Colleton County boundary. It is said to be so named from wagons using it to carry (fence?) wire from Orangeburg.
Pregnall is centered where County Highway 135 runs into U.S. Highway 78. A well known family name of early landowners in Dorchester and Charleston Counties.
Rosinville is centered around the crossroads of U.S. Highways 15 and 178. It was so named because it is a shipping point for the products of the pine tree, including rosin.
Ridgeville was formerly called Timothy Creek for a nearby stream. It was renamed Ridgeville in 1842, because of its situation on a pine ridge.
St. George is the county seat. There are two theories concerning the origin of the name: 1. In colonial times the section was included in the Parish of St. George, Dorchester. 2.

When the town was incorporated the name was given as St. George.
