I like Talitha. It was on a short list for one of our girls.
Also like Eve, (or Eva?) Esther, Rebekah, Johanna, Anna, Eden, Faith, Grace, Hope, Keziah (this one can be pronounced many ways - KEE zee ah, keh ZY ah, or KEH zee ah. The last is my favourite.) Mercy, Selah (I believe it's usually pronouced SAY lah) Tirzah (TEER zah, I think.)

You can also look at biblical boy names and feminize them, if you like. If this baby was a girl, she would be Matthea (mah TAY ah.)
Gabrielle, Michaela, etc.
