It's growing on me, too. I don't know if you're familiar with the play or Broadway show Spring Awakening, but one of the main characters is named Moritz. It's my favorite musical, so the name automatically brings to mind that character for me. That being said, considering what happens to him (don't want to give anything away if you haven't seen it) I'd be hesitant to actually use it. Another character is Melchior and that's growing on me, too. Wendla as well. I've just got Spring Awakening on the brain lately.
