Carolina in The Reivers (Location)

Like John and Jenny Sartoris, Lucius Priest I is originally from "Carolina" (as with the Sartorises too, the text does not identify which "Carolina," 278). But unlike the Sartorises, the Carolina Priest, Lucius' unnamed father, is a non-commissioned rather than a commissioned officer in the Confederate army, suggesting that he is not a member of the planter class. But if we can assume this home is not a plantation, we know nothing else about it.
