I don't care for
Aeron. It looks like a kre8tiv spelling for Aaron/Erin, even though it's not. And I don't care for the pronunciation, which makes me think of "I run." You'd have to be careful with the last name (i.e.
Aeron Miles...lol).
However, I've never seen Aerona before but I think the pronunciation is gorgeous. Very nice. :)
