Like many of the inhabitants of Yoknapatawpha throughout Faulkner's fictions, the lock which plays such a large role in the history of Jefferson originated in "Carolina" (6). Here, as typically, Faulkner does not say which Carolina, but South is more likely than North.
In both "A Name for the City" and Requiem for a Nun, just before the settlement gets its name, Doctor Peabody says that "we already got a church" - "Whitfield's cabin" (213-14, 23). The basis for his claim is probably that Whitfield (who does not otherwise appear in person) holds some kind of regular religious service inside his cabin.
After the jail break in both "A Name for the City" and Requiem for a Nun, the settlers look for the missing padlock "among the bordering thickets of their punily-clawed foothold" in the wilderness (208, 16).
In "A Name for the City" the first settlement that grows up around the Indian agency is described as "a half-dozen log cabins set in a disorderly huddle in the middle of the wilderness" (200).

According to both "A Name for the City" and Requiem for a Nun the name of the city - Jefferson - is first spoken in a stall in "the Holston House stable" (213, 22), where "Thomas Jefferson Pettigrew" is grooming the horse he rides back and forth between the settlement and Nashville (214, 23).
