Sibling names for Alessandra

We are currently ttc and we have a few ideas for possible boy names but are completely stuck on girls names. All the names that I used to like just don't seem to match up to Alessandras name.

I don't want our next daughter (if we have one) to be jealous of her big sisters name because her own name is boring or plain. I tend to like classic timeless names (though for girls I would rather the name not be top 50), I also don't want it to start with an A and feel like it's important for it to be as feminine and elegant as Alessandra...any ideas?!
