Middle name?

I love the name Bentley for a boy, I need help coming up with a middle name. I would like it to start with an "N". Old timey name or really unique preferred, any suggestions would be great though. TIA!

***Also, let me know of girls' names with the initials "B.N." please. I like Brooklyn and Braylin for a girl, but open to anything, and I have NO ideas on a middle name with "N" for a girl.***
