Having grown up in the deep south with a good ol'
German name like
Rilla, I'd have to say I wouldn't change them at all. That's the interesting thing about living in such a multi-cultural nation, you have a huge variety of names. As a school girl, I had friends named: Prizy, Myloe (a girl),
Imke, Frede, Tamasin, Maisha, Fa'Elle... The truth is that if the children don't make a big deal over their names, the vast majority of the other children won't either.
