Baby boy name help

We are team green, and if bebe is a boy we are struggling to find a good name for him! Middle name will be Arthur. Would prefer something not too popular.

Names I love but my husband vetoed: Sebastian, Viggo

Names we like but I would prefer something less popular: Jack, Henry

I love the name Kit but don’t like it on its own and don’t like the full names it’s often used as a NN for ( Christopher, Atticus). Please help!
