HEATHCLIFF
Is the central male character of the novel. A foundling raised by the Earnshaw family, he forms a bond with his foster sister Catherine Earnshaw and they share a passionate love, but it is founded on their sameness, of being different halves of the same soul, rather than just a romance or some physical attraction. Meanwhile he nurses a bitter rivalry with his foster brother Hindley, who resents the partiality his father shows Heathcliff and is cruel to him after his father's death. The only time he truly showed love or emotion was when it had to do with Cathy. He runs away from the heights when he is approximately sixteen (his age is unknown but he looks slightly older than Cathy) and returns three years later, having mysteriously made his fortune, education and refinement. He is a brooding, vindictive man, and his anger and bitterness at Catherine's later marriage to their neighbor Edgar Linton sees him engage in a ruthless vendetta to destroy not only his enemies but their heirs, a crusade that only intensifies upon Catherine's death.
CATHERINE EARNSHAW
She is Heathcliff's foster sister. She has dark brown eyes which are characteristic of her family. A free-spirited, wild, passionate, and somewhat spoiled young woman, she returns Heathcliff's love entirely, but because Heathcliff had been made so low that if she married them they would become beggars, instead she chooses another, Edgar Linton, through which marriage she hopes to help Heathcliff and bring him back to the standing he would have had. Heathcliff leaves the Heights after overhearing that it would degrade her to marry him, and because of this she throws herself into a violent fit and is ill for a while. When Edgar asks her to marry him she is about fifteen; they are married three years after Edgar's father's death when she is about eighteen, presumably when Edgar comes into his inheritance. When Heathcliff returns after those same three years she renews their friendship, which makes Edgar unhappy. Always on the edge of madness, her physical and mental health are destroyed by the feud between them, and she descends into prophetic madness before dying in an angelic state shortly after childbirth at about nineteen.
EDGAR LINTON
He is a childhood friend of Catherine Earnshaw's who later marries her. His fair appearance, blonde hair and blue eyes, contrasts with Heathcliff's dark appearance. A mild and gentle man, if slightly cowardly and distant, he loves Catherine deeply but is unable to reconcile his love for her with her feelings for her childhood friend Heathcliff. This leads to a bitter antagonism with Heathcliff, and it is partly this which leads to Catherine's breakdown. He is well-mannered and gentlemanly but always remains something of a spoiled child. He is too afraid to fight Heathcliff and shows fear at the prospect, earning both Cathy's scorn and solidifying Heathcliff's contempt. Linton is incapable of competing with Heathcliff's guile and ruthless determination across the decades, and his health fails him while still a relatively young man.
ISABELA LINTON
She is the younger sister of Edgar who becomes infatuated with Heathcliff. She fundamentally mistakes his true nature and elopes with him despite his apparent dislike of her. Her love for him turns to hatred almost immediately, as she is ill treated both physically and emotionally and held captive against her will. When Heathcliff returns from the Grange after Cathy's death she taunts him and he responds by trying to attack her, but Hindley interferes and she escapes the Heights. She leaves for London after visiting Nelly at the Grange and gives birth to their son Linton Heathcliff about seven months later, whom she attempts to raise away from Heathcliff's corrupting influence.
HINDLLEY EARNSHAW
He is Catherine's brother and Heathcliff's other rival. Having loathed Heathcliff since childhood, Hindley delights in turning him into a rough servant upon inheriting Wuthering Heights, making him work the fields. However, his wife's death from consumption destroys him; he becomes a self-destructive alcoholic and gambler and it is this that allows Heathcliff, upon returning to Wuthering Heights, to turn the tables and to buy the mortgage to Wuthering Heights which Hindley created because of his gambling debts, and to become its owner.
ELLEN (Nelly) DEAN
The housekeeper of both Thrushcross Grange and Wuthering Heights, and is the primary narrator of the novel, told through M. Lockwood's journal entries. She is Hindley's, Heathcliff's and Cathy's foster-sister and servant, and is the same age as Hindley, seven years older than Cathy. Heathcliff genuinely likes her and is always glad to see her. She recognizes early on that Heathcliff is Catherine's true love and tries to dissuade her from the disastrous marriage to Edgar. Having been a disapproving witness and unwilling participant to many of the events between Heathcliff and both the Earnshaw and Linton families for much of her life, she narrates the story to Lockwood during his illness at the Grange. It is presumed that she never married as she keeps the name Dean throughout her life. It could be considered that she is the true hero of the story, and without her many of the events in the story would never have taken place; however, she is not the primary protagonist.
LOCKWOOD
Lockwood's narration forms a frame around Nelly's; he serves as an intermediary between Nelly and the reader. A somewhat vain and presumptuous gentleman, he deals very clumsily with the inhabitants of Wuthering Heights. Lockwood comes from a more domesticated region of England, and he finds himself at a loss when he witnesses the strange household's disregard for the social conventions that have always structured his world. As a narrator, his vanity and unfamiliarity with the story occasionally lead him to misunderstand events.
