"...with a horrible great fang on it, really, Bill, what do they say at the bank?"
-- Molly Weasley (GF5)
William Arthur Weasley (Bill) is the oldest child of the Weasley family and is an adventurous person who works for Gringotts. Bill is married to Fleur Delacour.
The oldest son of Arthur and Molly Weasley, Bill is a caring, noble wizard who can’t resist a bit of “adventure and glamour” (HBP5). Slim and tall, Bill dresses as though for a rock concert (GF5), and is a capable wizard, earning O.W.L.s in all twelve subjects (CS4). When there was trouble at the Quidditch World Cup, Bill rolled up his sleeves and waded into the fray in support of the Ministry wizards (GF9), and when Mad-Eye Moody was killed, Bill was the first to volunteer to try to recover his body (DH5).
After leaving Hogwarts, Bill went to Egypt to work as a curse-breaker for Gringotts (CS4). However, when Voldemort returned he requested a transfer to a desk job in London so he could join the Order of the Phoenix (OP4). He joined the Order in battling Death Eaters at Hogwarts in June of 1997; during the fight he was savaged by the werewolf Fenrir Greyback. However, he survived with only some scarring and a penchant for raw meat (HBP29, HBP30).
While working in London, Bill started dating Fleur Delacour (OP6) and a year later they became engaged, much to his mother’s dismay (HBP5). However, after Bill was attacked by Greyback and Fleur affirmed her love for him, even Mrs. Weasley came around (HBP29). They were married on August 2, 1997, at the Burrow (DH8), after which the couple moved to a beautiful seaside cottage near Tinworth (DH23). Charlie was the best man at his wedding (DH6)
Bill has an easy-going charm and gets along well with his family. His cottage in Tinworth was the only place Ron felt he would be welcomed after he ran out on Harry and Hermione (DH20). He also treats his mother with respect, though he held his own when she wanted to get rid of his fang earring or trim his hair (GF10). He also believed very strongly in the mission of the Order of the Phoenix, graciously allowing his cottage to overflow with house guests though he didn’t know what was going on. Harry felt bad relying so much on Bill and on Fleur, but neither ever complained (DH24, DH25).
Bill and Fleur fought bravely in the Battle of Hogwarts. In the ensuing period of peace and rebuilding, Bill and Fleur had three children: Victoire (born one year after the battle), Dominique, and Louis (DH/e, BLC, YL).
Mother: Molly (Prewett) Weasley.
Father: Arthur Weasley.
Maternal grandparents: Molly and Sirius are "cousins by marriage," (OP6) so Molly's parents are probably related in some way to the Prewetts listed on the Black Family Tree (BFT).
Paternal grandparents: Septimus and Cedrella Weasley (BFT).
Aunts & Uncles:
- Weasley: Arthur had 2 brothers, but we don't know their names (JKR). According to Jo, Ginny is the first female to be born into the Weasley family in generations, so we can deduce that Arthur had no sisters (JKR).
- Prewett: Molly's brothers Gideon and Fabian Prewett (OP9).
- Surname unknown:
Cousins: Mafalda, a cousin who never made it into the books (JKR) and her father the Muggle accountant (PS6).
Siblings: Charlie, Percy, Fred, George, Ron, and Ginny.
Grandparents: Grandfather who originally owned Ron's "old and battered" wizard chess set (PS12). This grandfather could be either grandfather Prewett (Ignatius? BFT) or grandfather Weasley (Septimus? BFT).

Location of adult home: Shell Cottage, near Tinworth (DH23).
Spouse: Fleur Delacour (DH8).
