[Nerwen]

No. I rather think this falls under the "extraordinary claims" principle. You'd need to find an actual direct statement to that effect in something Tolkien wrote. You see, these comparisons you draw– well, no offence, but I really don't think they amount to much. I suspect you could find as many similarities between any two characters, just chosen at random.

Anyway– sorry for the cold water– and welcome to the Downs!
