The "them" in the phrase "made them return her money" is the only reference in "Miss Zilphia Gant" to the people who own or work in the store where Mrs. Gant bought and then brought back a miniature cook stove (373).
In the last section of "Miss Zilphia Gant," the title character returns to Jefferson after a three-year absence, "in mourning," with "a plain gold band" on her hand, "and a child" (381). She tells people about "her second marriage and her husband's death" (381), but it seems most likely that this husband is a figment of Miss Zilphia's imagination and a way to explain that child. In any case, just like the painter whom Zilphia did marry, he's never given a name, and so effectively she remains 'Miss Zilphia' - the name the narrator uses throughout.
In "Miss Zilphia Gant," the one girl whom Zilphia has permission to visit and play with after school is not named or described, but after the two girls have grown up the narrative mentions her marriage (Zilphia herself makes the bride's "white gown," 374), and, after another four years, the birth of her first child, a daughter (for whom Zilphia makes dresses).
In "Miss Zilphia Gant," the town's postmaster teases Zilphia every week about the letters she receives from Memphis; although the letters "bear the return address of a private detective agency," he "rallies her on her city sweetheart" (379). Behind his "insincerity" there is apparently some "pity" for her (379).
The man who makes "Miss Zilphia Gant" a Missus is introduced as "a tramp painter," an itinerant whom her mother hires to repaint the dressmaking shop. His last name is never given, so we cannot know Zilphia's married name. Her husband is described as "a young man with black hair and eyes like wood ashes" (375). Despite his own prejudice against any "woman that wore glasses" (377), he falls in love with Zilphia, and vows to her to "get you out of" the miserable life her mother forces her to live (376).
In "Miss Zilphia Gant," Mrs. Gant "borrows a pistol from another neighbor" when she leaves the Bend to get revenge on her husband (369). We know this 'other' neighbor is not the woman with whom she leaves Zilphia, but that is all the text makes explicit; that this neighbor's is male is our assumption.
In "Miss Zilphia Gant," Mrs. Gant asks a "neighbor" woman to "keep" Zilphia for her while she leaves to take revenge on her husband (369). This woman is never described.
In "Miss Zilphia Gant," years after learning that her former husband's wife is pregnant, Zilphia begins "to dream again" (380). The dreams that feature "negro men" cause her to "wake wide-eyed" (380).
In "Miss Zilphia Gant," the other men who frequent the tavern where Gant stays on his trips to Memphis are described as "rough, unshaven, overalled men" who "eat coarse food and drink pale, virulent corn whiskey and sleep in their muddy clothes and boots on the puncheon floor before the log fire" (368). Some of them, at least, are probably mule or horse traders like Gant - they arrive in "other caravans similar to his" - but others make their living in "more equivocal" but unspecified ways (368).
