Arthur Holmwood

He is engaged to Lucy Westenra, and is best friends with the other two men who proposed to her on the very same day—Quincey Morris and Doctor John Seward. In the novel he is the one who drives a wooden stake into Lucy after she becomes a vampire and helps hunt down Count Dracula. In the middle of the story Holmwood's father dies and he succeeds his father as Lord Godalming. It is mentioned in the note at the end of the novel written seven years after Dracula's death, that Holmwood is now happily married.
It is of interest to note that Holmwood and Jonathan Harker exchange personality types depending on whose significant other is being terrorized by the Count. In the beginning, Holmwood is emotional and prone to fits of depression while Jonathan attempts to maintain a strong will and recovery after his time in Dracula's castle. After the death of Holmwood's father, he gains a somewhat stronger will, befitting on his new title, while Jonathan is constantly breaking down as his wife is terrorized by the Count.
