Actually, I read a story in a newspaper last summer or whenever it was, about this guy, they wrote a good bit before they casually dropped his name into a sentence. His name was Gandalf
Appearently, it's an ancient Norwegian name from the Edda, but really, no-one here is going to relate it to anything but Tolkien.
I always liked the idea of naming a girl Tinúviel, Tina for short, but I'm not sure about boys' names. A friend of mine once said that she couldn't marry a man who wouldn't agree to name his son Aragorn..
