One of Roth Edmonds' grievances against Lucas Beauchamp in Go Down, Moses is that, when he would speak to the white man in the presence of "a group of young negroes," he would "lump" black and white "all together as 'you boys'" (112).
When Ike tells the younger hunters in the "Delta Autumn" chapter of Go Down, Moses about the old days "when I first started hunting in this bottom," he mentions that among the men who hunted with him was "Will Legate's" grandfather (328).
As part of his description in Go Down, Moses of Reconstruction in the South, Ike McCaslin imagines "women crouched with huddled children behind locked doors," seeking shelter from threats that are not named in the text, but are clearly meant to be understood as a consequence of the defeat of the (white) South and the emancipation of the (black) South (277).
Roth Edmonds meets with these unnamed friends after church in "The Fire and the Hearth" chapter of Go Down, Moses; their farm is eight miles from the Edmonds plantation.
An A[rmy] P[rovost] M[arshal] is the head of a unit of military police. This "Federal A.P.M." in Go Down, Moses is one of the Yankee troops who are stationed in Mississippi as part of the post-war Reconstruction (277). He has a black mistress, the sister of Sickymo, which is why he ensures that Sickymo is made a marshal in Jefferson.
In Go Down, Moses this "bank president," who tells Ike about the bank account in Ike's name that Cass Edmonds has been paying money into (295), is certainly not Bayard Sartoris, who is also a Jefferson bank president at the time of the novel. This "bank president" is never named, but although the text is not explicit, it seems likely that he is the father of the woman - also never named - whom Ike marries.
The three paragraph introductory to Go Down, Moses says that "some of the descendants" of the former McCaslin slaves are named McCaslin (5), but curiously no such characters appear in the rest of the story. There the family name of the many people who are descendants of Carothers McCaslin and his slaves is Beauchamp. (There are some of these descendants named McCaslin in The Reivers, published twenty years after Moses.)
In both "A Point of Law" and Go Down, Moses the signature of this "nameless clerk" appears on the marriage license for George Wilkins and Nat Beauchamp (221, 70).
The black woman who cooks Roth's food does not appear directly in Go Down, Moses, but he does speak to her "through the kitchen door" when he wants her to bring Lucas into the house (125).
