I think I have narrowed it down to two names, some opinions would be lovely...

I thought you had it down to a few. lol.
I like Freya and Pania. In my opinion Harper doesn't flow nicely with Sofia like the previous options did. I wish I was Italian... so many pretty names that I would just feel silly using with no Italian heritage at all.
I think Ariella would get boob jokes made at her expense. Kids really aren't very nice.
