Need boy name ideas!

I have a hard time coming up with boy names! I prefer names that are unique and not too common or popular. (no John, Michael, Tyler, etc.) but not super weird. I really like names like Theo, Liam, Asher, Wilder, Milo. The last name is Nelson. I would like to stay away from names that start with a B (my name) and J (my partner's name), but would maybe consider it if I absolutely love it! Would love to have the name go with the middle name Walter! (my partner's middle name and his great grandpa's name). Let me know what you got!!
