Perhaps Locksley is a duchy within the Kingdom of Camelot?

Because Robin has introduced himself, on more than one occasion, as Robin of Locksley, which is his more noble title.

And as for King Richard and King John being real, I think in this case you could still work with it, because there is a lot of legend that has built up around those characters as well. There may very well be similiarties between the Real LIfe Richard and the Richard of Robin Hood legend, but those do not have to be the same person.
