I've so been meaning to get around to his, woo productivity.
Xavier Avery: He's still fresh and new but it would be super awesome to have his wife around. Marissa Avery (Jugson) is pretty much a blank slate personality wise for anyone that wants to take her on. A Slytherin from '41-'48 she started dating Xavier while working as a Ministry Secretary and they got married out of LOVE, take that parent planned arranged marriages. Why should someone pick her up? Because think of the family drama going on!! Dead kids? That's a meal enough right there.
And then Filemina Attleyfidgeter has big brothers, Castor and Gunter, who apart from age and houses are free reign. Fil's family, especially mum and pop Richard and Maureen, tend more toward purist than not. They aren't flat out supporters of Voldy's reign of murder and terror but do have a healthy dose of ignorance inspired prejudice. Fil thinks that's a load of crap and is another reason she's mostly the black sheep of the family. Either on her side or her parents it'd be fun for some familial interaction here, parents or siblings.
Marissa would be awesome, so would one of Fil's brothers so if anything strikes you or you want to share an idea, hit me here or email or aim, whichever works :)
