Philip is "a grave, sober young man of impeccable character and habits" who courts the title character of "Elly" with clock-like regularity (213). As a Jefferson boy whom she has known "from childhood," Philip is the epitome of a suitable husband for Elly (213). His draw as a suitor is indicated in the same breath as his current occupation: "an assistant cashier in the bank, who they said would be president of it some day" (213).
The title character of "Elly" is eighteen years old. She "lives in Jefferson . . . with her father and mother and grandmother in a biggish house" (208). Elly has inherited her given name, Ailanthia, from her grandmother, a link that Faulkner uses to underscore the generational tension between the grandmother's Victorian sexual repression and Southern racial prejudices, and Elly's restlessness with these taboos.
There is a lot that "Elly" never explains about Paul's character - where he lives, for example, and what he does - but the one mystery that matters most is his racial identity. Paul visits Jefferson as a white man, but the friend who introduces him to Elly insists he is really black. As part of her proof, she recounts a story in which Paul's "uncle killed a man once that accused him of having nigger blood" (209).
Sutpen's "nearest neighbor" in "Wash" lives a mile away from his plantation; when after the war Sutpen gets too drunk to get home on his own from the store, Wash walks to this man's place and borrows a wagon to carry him in (540).
