Naming help!

My husband and I are expecting our second little girl in August💕🥰 For our first it seems like we had a whole list of names for her and plenty to pick from when we got to the hospital. For our second we are completely stumped. We have the original names but none of them go with our first daughter’s name. What names do you think go with Delta?🤔 New baby’s middle name will most likely be Renee.
