The "Mamma" of the narrator of "Uncle Willy" appears in the text only as the person Mrs. Merridew phones to complain about Willy's new wife (236). Her son does not describe her own reaction to Mrs. Merridew's rage.
"Papa," as the narrator of "Uncle Willy" calls his father, is a "lawyer" (236). Although he does not share any of the self-righteousness of the women who want to save Willy from his vices, he does participate in Mrs. Merridew's campaign to force Willy's wife to leave town, and in Job's attempt to keep Willy from flying his airplane. He calls Willy a "lunatic" (239) and blames the old man for the narrator's various forms of truancy; the narrator himself repeatedly rejects both those interpretations.
Although the narrator of "Uncle Willy" has a particularly close relationship with Willy, he is also one of the group of twelve- to fourteen-year-old "boys" who "see a lot" of Willy, in two very different contexts (226). They stop by his drugstore after their baseball games, where he feeds them ice cream while listening to their accounts of the games, and they watch him inject morphine; he joins them in church as a member of Mr. Barbour's Sunday School class for boys.
At the beginning of "Uncle Willy" the narrator identifies "the good women in Jefferson" as the people who are to blame for "driving Uncle Willy out of town," and thus for the narrator's own choice to follow him (225). The crusade against Willy's behavior is led by two particular women, Mrs. Merridew and Mrs. Hovis, yet at points the narrative seems to see the town's "good women" and the town's 'white' women as essentially synonymous.
In "Uncle Willy" Secretary is the name of the "negro boy" whom Willy hires to drive his car (235). In Faulkner's South, even adult black men are often called "boys" by white people, so although the juvenile narrator says that Secretary is "about my size" (235), he also says that Secretary is "older than me" (241) - though we have no way to know how much older. Both the narrator and Willy describe Secretary as "burr-headed," i.e. with short, bristly hair (235).
"Sister Schultz" in "Uncle Willy" is probably Reverend Schultz' wife (229). Like "Brother Schultz" and "Brother Miller" (229, 227), the title "Sister" most likely is a ceremonial title, indicating their fellowship as members of the same church.
Reverend Schultz is "the minister" of the Protestant church that both the narrator and title character of "Uncle Willy" attend (227). Along with Mrs. Merridew, he leads the campaign to "cure" Willy of his addictions (232). The narrator, who admires Willy Christian but not the town's 'Christians,' describes Schultz in the Sunday school class for adult men this way: "sitting in the middle of them . . . like he was just a plain man like the rest of them yet kind of bulging out from among the others like he didn't have to move or speak them reminded that he wasn't a plain man" (228).
The man whom the narrator of "Uncle Willy" calls "Uncle Robert" (239) is presumably his biological uncle, the brother of his "Papa" or "Mamma" - although given the other "Uncle" in the story (i.e. Willy, who is not related to the narrator), and the way Southern culture often uses the term ceremonially with white as well as black men, it's hard to be certain of that.
"Brother Miller" leads the adult men's Bible study class at the Protestant church that the narrator of "Uncle Willy" attends (227). In his case, "Brother" is a ceremonial title, reflecting his place in the church fellowship. Willy reluctantly leaves the boys' class in Sunday school to sit in with the "men" (227).
Mrs. Merridew is the character whom the juvenile narrator of "Uncle Willy" casts as the story's main antagonist: when he accuses Job of telephoning "Her" about Willy's whereabouts, both he and Job know he means Mrs. Merridew (246). She is a member of Reverend Schultz's church and the determined leader of the crusade to "save" Uncle Willy from his predilections, which she sees as both beastly and sinful (238).
