Victoire is the daughter of Bill and Fleur Weasley.
Harry’s son, James, caught Victoire snogging Teddy Lupin on Platform 9 ¾ as she was preparing to leave for what was most likely her seventh year at Hogwarts; at the time she would probably have been seventeen, and Teddy nineteen (DH/e). She was born on May 2nd, the anniversary of the victory over Voldemort (YL).
Mother: Fleur Delacour
Father: Bill Weasley
Siblings: Dominique Weasley and Louis Weasley.
