Mary Garth is the eldest daughter of Caleb and Mrs. Garth. She is plain-looking but intelligent, pragmatic, honest, and honorable. She cares for Featherstone while he is dying. Although she is continually frustrated by Fred’s bad behavior (particularly after he loses her family’s savings), she remains devoted to him. They eventually get married and have three children. Mary publishes a successful children’s book but gives the author’s credit to Fred.
