Pip Radish,
I have often expressed my disgust at the use of the title 'Edward' simply because it's the one Child felt compelled to use. It is the only known version that has the name, being an antiquified literary version sent to Percy by a Scots Laird and published by him in Reliques. Since Child's time many English, Scottish and American versions have turned up, none of them using the name 'Edward'. The Percy version was hailed by many literary people at the time, but it was like something out of Chaucer. Unfortunately the version the poem was concocted from hasn't survived.
