Need boy name suggestions!

I’m due in May with our second. We have a boy named Graham. We’re waiting on gender, but we already have a girl’s name picked. Just need a boy’s name! We like classic but not too common (so sadly even though I love Liam and Ethan, those are both out of the running!). We’re leaning Aidan (spelled like that), but we’re not committed and very open to suggestions! Thanks!!
