I was all set on using Penelope for the main character but it just didn't feel right as I have a family member with the same name.

So I think I will go with Annabelle (nn Anna).

I've been researching surnames for a whole day and can't come up with anything!!!!!

I need something that is European sounding but would often hear in Australia - so it can't seem too out there - the family name needs to fit in Australia KWIM?
