Baby name!! Help!

My father who I loved dearly passed away this past February. Fast forward to May.. I found out I'm pregnant. We recently learned we are having another boy! I really really want to honor my dad by naming this son indirectly after him. Problem is, he has an older name. Lol. William Eugene (but he went by Billy).. I would really love to give baby a W name, but can't find anything fitting. Reaching out to see what you guys may suggest? Help!!
