William Arthur "Bill" Weasley (b. 29 November, 1970) was the first child of Arthur and Molly Weasley (née Prewett) and the eldest brother of Charlie, Percy, George, Fred, Ron, and Ginny. He attended Hogwarts School of Witchcraft and Wizardry from September 1982 to June 1989, and was both a prefect and Head Boy. After graduating, he went to work for Gringotts Wizarding Bank as a Curse Breaker, working in Egypt. In 1995, he returned to England and joined the reconstituted Order of the Phoenix to face the reborn Lord Voldemort. During this time, he started dating Fleur Delacour, and eventually asked her to marry him after a year of seeing each other.
During the Battle of the Astronomy Tower, Bill was severely injured by the werewolf Fenrir Greyback. Although he did not become a werewolf, he did develop some wolfish tendencies such as a liking for very rare steaks. He married Fleur on 1 August, 1997, although their wedding was disrupted by the arrival of Death Eaters following the fall of the Ministry of Magic. Bill and Fleur then moved to Shell Cottage, where they assisted Harry, Ron, and Hermione after their escape from Malfoy Manor. Bill later fought in the Battle of Hogwarts alongside the rest of the Order, and survived the battle. Following the war, Bill and Fleur had three children: Victoire, Dominique, and Louis.
