I like austenteaparty's idea of Audrey if it's a girl. (I love the name Audrey) Goes great with Claudia ... I'm not that huge Hillary fan, sorry

Have never heard of the name Ari for a boy .. but it sounds really cool. No, wait ... I have, but we spell it differnt (Arrie) and say it more flat.
Ari for boy or girl ... would sound good, IMO

In the end ... it's your daugther/son, so what ever you feel would work.

Goodluck chosing!! And welcome to BB
