You're looking for honest opinions, right? This is going to sound harsh but I am not going to sugar coat it.
1 being worst 10 being best:
Mia Lynn 1
Angel Elizabeth 3
Lizzie Leigh 1
Callie Lu 1
Lily May 5
Kayla Sam 1
Different middle names would be better for most
Mia is cute but does not go with Lyn
Angel reminds me too much of the TV show with vampires - and Angel was a male.
Lizzie is horrible as a name. Elizabeth is beautiful, but leigh does not fit.
Callie is cute but better as a nickname for Clarissa, Claire, Clarine, Clarina. I have seen it spelled Calleigh before. Lu is awful.
Lily May is really cute but sounds very southern. It is my favorite on the list, but I would spell it Lilly Mae
Kayla is pretty, Sam is not. How about Kayla Samara?
