Byron has four children with an Apache woman in New Mexico. They are probably all legally illegitimate, and all are wearing overalls when they get off the train station in Jefferson. None are named, but two are specifically identified as "boys" (378). Charles Mallison's narrative does not differentiate between these boys.
Byron Snopes has four children - probably all illegitimate, legally - with a Jicarilla Apache in New Mexico. According to Charles Mallison's narrative in The Town, "the tallest was a girl though we never did know whether she was the oldest or just the tallest" (378); like her brothers, she is wearing overalls when she arrives in Jefferson. (All four children are mentioned in one phrase in The Mansion, as Byron's "four half-Snopes half-Apache Indian children, 327.)
This "Jicarilla squaw" from "Old Mexico" is the mother of "Byron Snopes's children" (379), the four sinister kids who appear at the end of The Town and then, as soon as Yoknapatawpha realizes how dangerous they are, are sent back into the west. She is mentioned, barely, in The Mansion, but nothing more can be said about her.
Doris Snopes is the youngest brother of of Clarence Snopes. He "resembles Clarence not only in size and shape but [has] the same mentality of a child and the moral principles of a wolverine" (327). He appears only in The Mansion.
Vardaman (and his twin brother Bilbo) are minor figures in The Town and The Hamlet, one of the three (or four, in the second novel) sons of I.O. Snopes and his second wife. Also like Bilbo, he is named for one of the segregationist politicians in modern Mississippi politics, in his case for James K. Vardaman, a very outspoken white supremacist who served as both a Governor of Mississippi and a United States Senator.
Bilbo is a minor figure in the last two volumes of the Snopes trilogy. In The Town he is the son of I.O. Snopes and his second wife and the twin to Vardaman Snopes. Not even that much is made clear when he is briefly mentioned inThe Mansion. He is named after Theodore G. Bilbo, a Mississippi Governor and U.S. Senator who was a staunch defender of white supremacy.
On the Snopes family tree, Clarence - according to The Mansion, it's "pronounced 'Cla'nce'" (325) - is the son of I.O. and the half-brother of Montgomery Ward Snopes. He is one of the four Snopes named in Faulkner's first Yoknapatawpha fiction, Flags in the Dust, but appears only as the boy whose "hulking but catlike presence" makes Bryon Snopes nervous (235). It is in Sanctuary that his character as one of the most venal Snopeses emerges.
Montgomery Ward was named for a national retailer (Montgomery Ward) that specialized in selling by mail to rural customers. The son of I.O. and his first wife, he is among the first Snopeses Faulkner ever created. He doesn't appear in Flags in the Dust but is mentioned there when Horace Benbow's neighbor asks him about "your Snopes" (166). After faking a heart condition to evade the draft, Monty had accompanied Horace Benbow to World War I as a non-combatant working with the Y.M.C.A.
As a child, a hulking and "bear-shaped" figure, Saint Elmo eats all of the candy in Varner's case (350). A son of I.O. Snopes from his first marriage, he appears only in The Hamlet. (The names of the various Snopeses come from a variety of sources; Saint Elmo's name comes from the title of an 1866 novel by Georgia author Augusta Jane Evans.)
Faulkner's decision in The Town to make I.O. Snopes a bigamist complicates the identity of the various characters who appear as his wife. The first such character appears in the first Yoknapatawpha fiction, Flags in the Dust, as a "placid mountain of a woman" who spends her days in the porch swing of their "small frame house" - "not doing anything: just swinging" (235). Her son is named Clarence.
