Ælfheah

This is a great name, very unique!

I'll admit that the meaning of "elf high" is a little bit weird to say the least. Furthermore, I find it unspellable and quite possibly unpronouncable.

A kid named ... I'm not even going to try to type it ... would definitely have trouble in school when there was a substitute teacher. Don't you remember how it felt when they couldn't pronounce your last name? A kid named ____ would have issues with their first name, too.
