First name help

We want to use the middle name Billie for baby girl. We can’t decide on a first name. I’m thinking something ending in the “uh” sound is best. but I also like r sounds. 

Examples:
Ila Billie
Aster Billie

mb0112

I like Isla (this spelling). I'd avoid names like Aster that are not clearly feminine unless you are aiming for gender being hard to guess based on the name. 

Eleanor
Mia 
Clara
Freya 
Fiona
Piper
Margot
