HELP! We need name spelling suggestions!!

I am due any day now with my third son and we’ve been struggling with how to spell his name. We have always done family middle names for their middle names, so we were thinking Ray or Raymond. The first name we can’t decide if it should be Rowan or Rowen. Any advice??? Would you spell it with an “a” or an “e” and why??

EDIT: Any cool middle name suggestions that go well with our first name choice would be amazing to ponder over!!
