The very fact that his name is "Sir" Kay pretty much rules out the manservant. People that are knighted are generally not manservants, generally speaking.

I honestly think we are so fixated on it being associated with Arthur directly, that I think it may have nothing to do with Arthur, and very little to do with Camelot even.
