Fleur Isabelle Delacour was the Beauxbatons champion for the 1994 – 1995 Triwizard Tournament (GF16).
Initially, Fleur is a bit haughty and dismissive. She attended the Yule Ball of December 1994 with Roger Davies of Ravenclaw, criticizing Hogwarts for everything from its food to its decorations in a voice loud enough to be heard by everyone around (GF22, GF23). She was still somewhat critical almost two years later (HBP5).
Boys (and grown men) find her extremely attractive, but girls -- particularly Hermione and Ginny -- are usually a bit less than taken with her. She is conscious of her beauty and her power over men; this is at least in part because of her Veela heritage.
When Harry came to stay with the Weasleys the summer of 1996, he discovered that Fleur was also visiting so she could get to know her future in-laws better. At first, the visit had mixed results: Ron was still dumbstruck around her, but her superciliousness grated on Molly and Ginny (HBP5). However, months later, when Bill was mauled by the werewolf Fenrir Greyback Fleur surprised everyone by standing by him and reaffirming that she wished to marry him "I am good-looking enough for both of us, I theenk!" (HBP29). The wedding took place at the Burrow on August 1, 1997 (DH8), the same day that the Ministry of Magic fell to the Death Eaters. Bill and Fleur moved to Shell Cottage, where they harbored a number of fugitives and victims of the Death Eaters (DH25).
Fleur and her husband fought bravely in the Battle of Hogwarts. In the ensuing period of peace and rebuilding, Bill and Fleur had three children: Victoire (born on the anniversary of the battle), Dominique, and Louis (DH/e, YL).
Grandparents: Her maternal grandmother was a Veela (GF18).
Father: Monsieur Delacour.
Mother: Apolline Delacour, a half-Veela witch.
Siblings: Gabrielle Delacour, a younger sister.
Spouse: Bill Weasley (DH8).
Children: Victoire, Dominique and Louis (DH/e, YL).
"Fleur Delacour" means "flower of the court," according to Rowling (AOL).
