Hey I was thinking, given the improbably nature of [i]all[/i] the heroes being named Link I was thinking that perhaps only a couple (mostly the first ones) where actually named Link but whenever the Legend is recorded regardless of the hero's actual name they put it down in the records as Link. If we sort of treat this like it's a story telling of one of the ancient legends then this would come into play.

Basically I think all I'm saying is that each of the heroes should be refered to as Link but no one should make any mention of how odd it is that all of them [i]are[/i] named Link. Even characters like Navi or Saria who would have known multiply heroes. If that makes any sense at all.
