Name: Onyx Mélina Bonheur
Age/Birthdate: 11/14 Jan 2099
Appearance or suggested face claims: As she's Wynter's twin, currently I have her FC set as the same: Kristina Maurer. But I'm open to them being fraternal instead of identical.
School/House or Occupation: St Woboldo's, soon to be Hogwarts (starting Sept 2110)
Family info: Parents are Alexandre Bonheur and Celestine Underhill (both NPCs. Dad is related to several of my Beauxbatons students/graduates and Mum is Dáire and Lennox Grenadine's aunt) Siblings are older brother, Andrew Armand Bonheur, and aforementioned twin sister, Wynter Maëlys Bonheur) family trees available by request
Personality Traits: open to the RPers interpretation, although I see her as sort of the straight man to her sister's fanciful thoughts (Wynter is an aspiring actress who idolizes Mozart Bronwyn)
Background Information: Mum and Dad generally support anything their children want to pursue, within reason. I mean, they support Wynter's going out for auditions and so forth so why would they not to the same for their other children? Pureblood on dad's side, halfblood on mum's.
