Baby girl name that starts with B!

Anyone have any ideas for baby girl names that start with B? My boyfriend and I are having a sweet baby girl, and her name is going to be Ainsley. However, we wanted a middle that started with a B. Since my name starts with A and so will hers, i liked the idea of having B for a middle name like her daddy’s first name. Just having a hard time coming up with a middle name that sounds elegant and flows with Ainsley! Any suggestions are helpful!!
