Baby Name Poll

I love the name Opal but my husband only likes it as a middle name because it's super vintage. We both definitely want her first name to be unique but not like "Lemon" unique, you know? And hubs is determined to not have a "grandma" name like Agatha. We want something that will be nice as a name, on any age, but she still won't share it with other girls at school. We have looked at quite a few names but still haven't found anything that stands out for both of us. Any ideas that will flow well with middle name Opal? Our surname is easy to pair names with so we aren't worried about that part. Thanks! ~Sydney
