What should I call my son (due at the end of April)

Im having difficulty finding names I like. I need two - three names that roll off the tongue and wouldn't be out of place with a long hyphenated surname.

No religious names

No surnames

No places

Nothing that rhymes with Aden

Upvote good suggestions otherwise post ones. Bonus points if it's a sci-fi name.

Edit: lots of good suggestions, but I think I'm going with 'Wash'.
