Hmmm, "Kit?" Have you read "Shadow of Night?" Good book and there's a very grim guy nickednamed Kit.
I originally went with Daniel, but when I looked it up it means "God is my judge." I'm not sure where he comes from, but Aaron might fit better because it means "strong." It really depends on where his name comes from. Were his parents artists, religious, or traditional? Or, did he eventually change his name? I know it's important to have the name reflect the character, but sometimes it's okay to have a name that doesn't necessarily fit (i.e. the name means strong, so he must have that name) . My final answer is Aaron. Although, if you want to go with a different name meaning strong, Wilhelm means "strong-willed warrior" and it could be a first or last name.

Sounds good :)

I think Daniel fits very well.

I picked Daniel even though none of my characters are very religious. He might be Jewish though and just not be active about it. thanks for voting :)

Daniel works too
