*Yes, Aberdine is a real girl's name.

**I am aware that Ted Tonks' real name is Edward, but in my head canon he is Theodore. This is because I actually thought his name was Theodore for about three years after Deathly Hallows was published. Also, the first time I wrote Teddy Lupin in a fic it was a Twilight crossover and I couldn't use Edward for obvious reasons.
