|Christine Rosier (née Rondeau)|
Christine Rosier (née Rondeau) was a french witch who attended Beauxbatons Academy of Magic and were part of their school's delegation to Hogwarts School of Witchcraft and Wizardry in 1994 for the Triwizard Tournament. They entered their names in the Goblet of Fire, and when Fleur Delacour was selected as the Beauxbatons Champion, they broke down crying in disappointment. They presumably remained at Hogwarts for the remainder of the school year to watch the Tournament.
In the Christmas holidays that year, Christine was invited by her classmate Michael Rosier to be her date for the Yule Ball. Christine accepted the invitation of the young and from the prom night they started dating. Christine knew the legacy of the black family of Michael, but still continued following him and helping him in his personal achievements. After graduating from Beauxbatons, Christine and Michael were married and living in France.
In 1998 they fought in some way against the followers of Voldemort that expanded the French town. At one point in 2005 or 2006, Christine became pregnant with a girl named Valerie, who in 2017 went to Hogwarts where she became a Slytherin.
