Baby name opinion!

We’re team green here due at the end of April! My boyfriend and I think we decided on the name Booker Frank if baby is a boy. Booker is my boyfriends middle name, and Frank is my late Grandpas middle name. Can I have some opinions on this from the outside looking in? We didn’t get very far on a girls name, he doesn’t like any on my list. The closest that he likes is Ella in which I like Ellie. Similar girl names would be helpful. 😂 Big sisters name is Ava Louise. 🥰
