#2 is great :)
Leo Conor is sweet! I prefer the Connor spelling but if you prefer Conor that's fine with me too. Adolf is a little Hitler-ish but I like the name and I think it's time that the names comes back :P Leo Wolfe os awesome! Arthur (meaning bear) is also one of my favorites (Leo Arthur?! Which one do you prefer out of Leo Conor/Connor and Leo Wolfe?
Nightingale Mina are two awesome names, but I prefer Mina Nightingale (love it!). Or Mina Aderyn?
