Bob Ewell and Mayella Ewell are Father and daughter of Maycomb’s poorest family.

Bob knowingly knows that Tom is innocent and still accuses him of rape.

Bob represents the dark side of the south; ignorance, poverty and racial prejudice.

Mayella is abused, lonely, unhappy daughter.

Although we can pity Mayella because of her father, we cannot pardon her for her shameful indictment of Tom Robinson.
