Many of the many Snopeses who appear in the fictions are "descendants" of Ab Snopes (6), but the specific group referred to in "Barn Burning" is made up of the unnamed Snopeses who are alive in "later years," later, that is to say, than the first introduction of automobiles into Yoknapatawpha - i.e. sometime after about 1920 (6). The narrative notes that the "same quality" that makes Ab handle his mules badly will characterize the way these future Snopeses try to "put a motor car into motion" (6).
"Monk" includes two separate visits to the state penitentiary, but the only specific reference it makes to the inmate population is when, during an "abortive jailbreak," Monk shoots the warden. "Fifty men" see him do that, and "some of the other convicts" overpower him afterwards (50). One of these men is later identified as Bill Terrel, and some of them, like Bill Terrel, are considered by the Governor's Pardon Board for release.
The narrator of "Monk" presents the Pardon Board as a "puppet Board" which remains "completely under" the thumb of the Governor (54-55). They are apparently appointed to the Board based on their ability to deliver votes for him.
After Mrs. Odlethrop dies in "Monk," these neighbors try and fail to catch the young Monk. The story describes the people of this part of the county as violent towards strangers, but in this instance it shows that they can treat their own with kindness: they bury Mrs. Odlethrop and leave food for Monk at the "deserted house" even though they don't see him (44).
If you believe what Bill Terrel says in "Monk," the man he killed seduced his daughter. But the daughter denies this, Terrel's story is not believed by the jury that convicts him of "Manslaughter," and the rest of Faulkner's story supports the idea that it is a lie (55). On the other hand, who this victim really was, or why Terrel killed him - that remains a mystery.
According to the narrator of "Monk," the murder victim at the gas station where Monk works and lives is "no loss to anyone" (46). And that is all the story says about him.
After Monk is arrested, he is unable to identify his supposed victim. As the narrator of "Monk" puts it, "he named as his victim (this on suggestion, prompting) several men who where alive, and even one who was present in the J.P.'s office at the time" (42). His ignorance here provides further proof of Monk's incompetence to participate in his own defense.
In "Monk" there are two unnamed men present when Monk is found holding a pistol beside a man who has been shot. This is the man who did not do the killing - though of course he becomes an accomplice when he refuses to tell the truth about who did do the killing.
In "Monk" there are two unnamed men present when Monk is found with a pistol in his hand beside the man who has been shot. This is the one who, five years later, confesses on his deathbed "that he had fired the shot and thrust the pistol into Monk's hand, telling Monk to look at what he had done" (49).
