Wuthering Heights

Catherine Earnshaw is Mr. Earnshaw's daughter and Hindley's sister. She is also Heathcliff's foster sister and love interest. She marries Edgar Linton and has a daughter, also named Catherine. Catherine is beautiful and charming, but she is never as civilized as she pretends to be. In her heart she is always a wild girl playing on the moors with Heathcliff. She regards it as her right to be loved by all, and has an unruly temper. Heathcliff usually calls her Cathy; Edgar usually calls her Catherine.
