Looking for a boy/gender neutral name to go with big sis Iris

We're expecting a boy later this year and are struggling with names!

We have a daughter named Iris and have been given so many lovely pieces of art, mugs, etc with irises. It feels like our house is a shrine to her so I feel like we need something along similar lines for our next kid but we are really struggling to land on a boy or gender neutral name. We are looking for non-religious names that feel like real names and aren't hyper-masculine.

Any help is so appreciated!

EDIT: Thanks for the input, everyone! I really loved readings everyone's suggestions and had a lot of fun with this. :)
