HELP baby girl names?!?

Samantha • Mama to two beautiful girls. 22 months apart. 💜☀️😍
My husband and I had a boy name picked out because we were told at a scan at almost 16 weeks that it was a boy, only to find out at our anatomy scan yesterday that it's a GIRL! Lol! 
We kinda like the name Olivia Grace (middle name is negotiable) but I'm just not sure. AHHH! Still in shock yet sooo excited that we're having another little girl.🙆🏽 Our 18 month old daughter's name is Aubree so I'm trying to stay away from "A" names again. Thanks in advance!!! 
UPDATE:
After texting back and fourth with my husband discussing names all day, and after talking more when he got home, we finally decided on what baby girl will be named!!!
