Name Aria

I wouldn't. Aria is an operatic term, same as in English, and it's either pronounced the same way, A-ria with emphasis on the first letter, or A-ri-a with emphasis on the middle part, or Ari-a with emphasis on the last letter. All three sound off for a name. I am guessing you'd use the first variant, A-ria, and that is very close to the Swedish pronunciation of the word "area", easily confused. I can also bet that children will find several ways of making fun of such a name. That's always a risk, but deliberately choosing a name that is clearly different is very inviting for bullies.
