I feel like in this situation, since you have already narrowed it down so much, wait until you meet him in person. It may help to see him first and perhaps you'll get an inkling as to what he should be called. I'm sorry not to directly answer your thread; I think they're both lovely. Julian is more of a steadfast classic, and Leo is strong and simple. So, which one is your baby? You won't know till you see him.
