Need a baby girl name!

My husband and I are having a hard time trying to come up with names for our baby girl. I am due in 3 weeks and am feeling the pressure! Please help! Her middle name will be Briannon with a Polish last name. Her sisters name is Ava.

how about:

Camille Briannon
Stella Briannon
Olivia Briannon
Eve Briannon
Juliet Briannon

Since her sister has a short name, how about something short as well:
Cara
Cora
Emma
Iris
Isla
Ivy (too similar?)
Jana
Joya
Lia
Lana
Lara
Lila
Lois
Mara
Maya
Nora
Rita (like Lana, name of a screen goddess, same vintage as Ava Gardner!)
Tara
Thea
Zara
Zoe

I like the Camille suggestion. Also:
Maya (same ending as Ava though, not sure if this bothers you)
Phoebe
Cora
Claire
Margot
Nina
Nora
Ainsley
Eliza
