Well I happen to see two beautiful names right there in your four names.

Savannah Grace

and

Audrey Claire

Seriously, I think they both sound great.
Audrey would also work as Audrey Savannah or Audrey Grace

If you want some different ideas, older names that are pretty are:

Bethany, Juliana, Caralyn(Carolyn or Karolyn),Holly, Laura, Megan, Roxanne or Roxanna(never seen anymore), Teresa(tess, Tessa, Tara, Tera),Susanna,Veronica.

Hope it might help!

One of my favorite girl names is Talia. It has a nice meaning and it is not too common. it means heaven's dew in Hebrew. I am sure you will find one in time. Also, even though you do not need to name your baby in the hospital, I have heard it is an ordeal with social security if you wait, so hopefully you will have a few names you like when you are in labor.
