Name help!

Sara • Mommy to Ayden Alexander & expecting a princess in Dec. 2015!
We've been looking at names for our little girl. Nothing is for sure yet because we are still thinking. But we are really loving these two names but also need a middle name help or other names in general that are like these: 
As for middle names I don't really care for the typical like Marie or Nicole(that's mine), but more unique or less used. 
Ideas are welcomed!
