Thoughts? Name - Aria Brynn

Hi ladies! 
We are 22 weeks along with a baby girl. We've tossed around tons of names and we really like Aria Brynn. Our last name starts with an M. What do you think? 
We also like Keira, Audrey and Alexandria for first names. 
I always heard people say how hard it is to pick a name but damn....this is so tough. So much to think about!
