baby naming!!❤

Casey
My boyfriend and I have have already picked a boy name if our second child is a boy. Collin Elijah. 
Now he picked out our daughters first name Gracelyn so if this baby is a girl I want to choose the name. I want to be unique. 
What do Amy of you think or aralina nicole.
The pronunciation is 
Air-uh-lee-na
Any thoughts?
