The introduction of the Grangerfords and Shepherdsons adds a new element of humor to Twain's novel. Whereas earlier Twain satirizes the actions of "common" townspeople, the stately families provide a perfect opportunity for Twain to burlesque the Southern code of chivalry and aristocracy of the antebellum South. The Grangerford's house represents a gaudy and tasteless display of wealth, and Huck's appreciation of the decor only adds to the humor. The decor that exemplifies the Grangerford's taste is the artistic work of Emmeline, the deceased daughter who pined away after failing to discover a rhyme for "Whistler." In contrast to Huck's practical fascination with death, Emmeline's work displays a romantic and sentimental obsession that even gives Huck the "fantods."
Twain also uses the families to underscore his subtle satire on religion, as the two families attend the same church, leaning their guns against the walls during the sermon about "brotherly love." The mixture of theology and gunplay is ironic, as is the family's subsequent reaction that the sermon was filled with positive messages about "faith and good work and free grace and preforeordestination." Twain's Calvinist background resurfaces in his combination of predestination and foreordination.
