Harold Baddrington is a pilot who serves with Charles Mallison during World War Two in The Mansion. He gets his nickname "Plexiglass" on account of his obsession with cellophane, "which he called plexiglass" (323).
"The only sister of old Major de Spain," Mrs. Allison in The Mansion is "a bed-ridden old woman living in Los Angeles" (463). She and her daughter end up owning 'the mansion' after which the novel is named. (If in Faulkner's imagination she is related to the Allison family that appears in the earlier short story "Beyond," the text doesn't say so.)
In The Mansion Miss Allison is the spinster daughter of Old Major de Spain's sister and "the retired principal of a suburban Los Angeles grammar school" (463). She is deeded the old De Spain mansion - 'the mansion' of the novel's title - by Linda Snopes Kohl.
Myra Allanovna in The Mansion is the Russian immigrant proprietor of an upscale New York store where she sells the neckties she designs. She is described by Ratliff as "a short dumpy dark woman in a dress that wouldn't a fitted nobody," but he adds that she has "the handsomest dark eyes I ever seen even if they popped a little" (186). (Faulkner almost certainly bases this character on Lucilla Mara de Vescovi, an Italian immigrant who opened Countess Mara, a men's neckwear company, in New York in the early 1930s; Countess Mara ties are still sold today.)
The title character of "Miss Zilphia Gant" learns from a newspaper about this woman "in another state" who marries the man to whom she herself had been married (379); from the detective agency she hires, Zilphia learns about "the birth of a daughter and of the mother's death," a sequence that suggests this woman died in childbirth (381). Although from the agency's reports Zilphia learns enough about this woman's marriage to live "vicariously" inside it (380), what the story passes on to readers is vague and confusing.
In "Death Drag" Jock is one of Faulkner's aviators who cannot stay away from airplanes: a former pilot in the Royal Flying Corps who has lost his civilian pilot's license but continues to fly nonetheless. He is a tall, dashing figure whose stained clothing and unruly hair indicate that he doesn't care about his physical appearance; insomniac and perennially thirsty, he is emotionally tense and self-contained and won't accept offers of help from his former comrade-in-arms, Captain Warren.
In "A Justice" "the Willow-Bearer" - his name never appears without the definite article - apparently performs an undefined ceremonial function related to the selection of the new "the Man" - the tribal chief whose title also always includes the "the" (349).
In The Sound and the Fury the conductor standing beside Quentin on the back platform of the trolley twice suggests that Quentin should "get a seat" inside the car (171).
In The Sound and the Fury Deacon tells Quentin that the reason he marched in the parade "on that Wop holiday" (presumably Columbus Day, 98) was to help his son-in-law "get a job on the city forces" as a "street cleaner" (98). Deacon also calls him "that son of a bitch," and implies he's very lazy (99).
Shreve is Quentin Compson's Canadian roommate at Harvard in two of Faulkner's greatest novels: The Sound and the Fury (where his last name is MacKenzie) and Absalom, Absalom! (where it's McCannon). In the first novel he's largely defined by his concern for Quentin's well-being, which apparently leads some of their fellow students in the novel (and has definitely led a few critics writing about the novel) to speculate that the bond between them may be homoerotic.
