Arlo is my favourite but agree it’s used by people who think they’re being quite unique.
Beau is cute as long as he is a gorgeous boy.
Abel - killed by brother. People might be mean if he’s not very “able”.
Bodhi - quite like the sound of this but don’t like the spelling. The Point Break link is a positive for me.
Other suggestions you might like: Brody, Jago, Ezra.
