Lions and humans are animals so I suppose in some strange spiritual level we connect. It is quite awesome, actually lol.
I LOVE searching for my character's name, I find out so many things and meanings along the way xD I love the names Dmitri and Frederick, so I usually use those two.
I really like Cade/Caden. Jules might be a good one too. I do suggest that you look up Victorian Era names or just old names OR combine two names and see what you come up with that. Good luck!
