According to a story that Elly's friend "just heard," Paul de Montigny has an uncle who "killed a man once that accused him of having nigger blood" (209). In the friend's mind, this story 'proves' that Paul himself is black, but while believing in 'black blood' as a kind of curse tells us something about the friend and the culture she grew up in, "Elly" does not allow us to say whether Paul even has an uncle, much less whether any of the friend's other assumptions and implications are true.
According to the friend in "Elly," this unnamed man was killed by Paul's uncle after he had suggested that the uncle was part black - or as the friend puts it, in language that reminds us that in the racist world of the story, such a 'suggestion' is actually an accusation, that the uncle had "nigger blood" (209). The friend says she "just heard" this story (209). Elly calls it a lie. So it's possible neither the incident nor the uncle ever existed.
Elly's unnamed friend entertains Paul de Montigny in her home, but is quick to judge Elly for the latter's interest in him. Elly's friend smokes, furtively, in her home, presumably hoping to escape detection by her parents. But if she too is rebellious, it is within very fixed limits. When Elly defends her behavior with Paul by reminding this girl that "you invited him into your house," she replies "I wasn't hid in the cloak closet, kissing him, though" (210). And despite entertaining Paul, she takes the signs of his mixed racial identity as proof of Elly's "queer taste" (209).
In the short story names after her, Elly stays in her cousin's room during her visit to her uncle and aunt in Mills City. The cousin herself does not appear, but her bedroom is filled with "the frivolous impedimenta of a young girl" (217).
Elly's mother lives with her, her husband and especially her mother-in-law in a "biggish house" in Jefferson (208). She is a negligible figure in her daughter's life, though it is her suggestion that Elly drive to Mills City to pick up that mother-in-law that precipitates the story's violent climax.
Elly's father lives in Jefferson with her, his wife, and especially his mother. He is a negligible figure in her life, dominated as it by his mother. The one time he and Elly are together, at breakfast, Elly thinks: "He said nothing, apparently knew nothing" (211).
Elly's grandmother - Elly's father's mother - lives in Elly's family's home in Jefferson, though she is formerly of Louisiana. Her given name is Ailanthia, as is that of the granddaughter after whom "Elly" is titled. Elly's grandmother is frequently described as cold: "cold, piercing" (209), with "that cold, fixed, immobile, inescapable gaze of the very deaf," having lost her hearing 15 years before the story takes place (212). The narrator calls her an "old woman whose hearing had long since escaped everything and whose sight nothing escaped" (223).
Although "Elly" begins and ends on the road between Jefferson and Mills City, the only other drivers mentioned in the story are referred to, obliquely, at the very end, after the accident, when Elly thinks, "They won't even stop to see if I am hurt" (224). Their presence is indicated only by the "snore of an engine, the long hissing of tires in gravel" that she hears on the road above her (223).
