Need help with girl names

mymidg

We're expecting our 3rd child in late September. We have a two girls named Mina Eleanor and Della Genevieve. For a boy we like Theo Augustus or Hal Augustus. We don't know the sex of our baby yet but are really stuck on girl names, Do you have any suggestions? Something short and feminine would be ideal. Thanks
