Middle name help!

Our son is going to be making his way into the world any day now and we still haven’t agreed on a middle name! We decided on Franklin for his first name (he will go by Frank). I love the idea of Wilder (I keep saying since he’s our second boy, he’s just meant to be wilder!) but my SO HATES it. He likes Dean but I told him no because Franklin Dean sounds like frank n beans. 🤦🏻‍♀️ help. I want something a little different but I can’t find anything we both like.
