These women and (mostly) men stay at Mrs. Littlejohn's "hotel" in The Hamlet. In the Ike Snopes' narrative, Faulkner refers to them as "last night's new drummer-faces" - i.e. traveling salesmen who are staying for one night (182). While they can be classified as a group, these individuals are constantly coming and going, staying in Frenchman's Bend for variable amounts of time. Typically only men stay in Yoknapatawpha boarding houses, but in this case we know that Mrs. Armstid stays at Littlejohn's while her husband recovers.
In The Mansion Mink remembers that when he was younger there was a Negro in "the lot behind the Commercial Hotel" who would feed his mule for a quarter while he took the train to Memphis (313).
This is the "doctor or officer" - Labove, who witnesses the event in The Hamlet, "does not know" which - who attends to a dying Negro who has been shot at on "a bleak station platform" at an unnamed location (138).
This is the woman whom The Hamlet refers to as the "curl-papered landlady" in El Paso who tries to prevent Jack Houston from taking the woman who becomes his common law wife away from her house - but since the woman is a prostitute and the place the landlady runs is a brothel, it seems clear that "landlady" is a euphemism for 'madam' (234).
After Houston returns to Yoknapatawpha in The Hamlet, he sometimes meets the "contemporaries" who remember him from the "youth" they shared, with whom he still occasionally gets together for "drinks or cards" (237).
