Help!!!

My husband and I are expecting baby girl #4. I have two girls from a previous marriage-Gracie Lane and Emma Kaylan and he has a daughter from a previous relationship-Avery Ellen Elizabeth. He had zero say in the naming of his daughter so I really want to find a name he agrees to but we are completely stuck and cannot agree on one for the life of us. We are due any day now and it’s getting down to crunch time. I like names that are different like Oaklyn but also love Stella and Sophia. He likes more traditional names like Penelope or Olivia. I just don’t want a super common name and I’m beginning to think our child will never have a name.
