Help! Boy #4!

Just found out babe #4 is a boy. I guess I’ll be a boy mama 💙 which is completely fine but we have THE HARDEST time agreeing on boys names. We currently have a Brentley ( named after dad, Brent) and Lincoln and Jaxson (twins). I’d like something that starts with a different letter than B,L and J. Middle name will likely be Allen after a grandpa. Please help! All suggestions and ideas welcome!
