Unnamed Man Paul's Uncle Killed

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.
