Hereward Wakes
This is heavily influenced by all my years spent doing Anglo-Saxon re-enactment. Also by the fact that we've just moved to the Fens, which is Hereward's country. He was a real Robin Hood, who held out against the Norman invasion for years. They tried everything to get rid of him, including bringing in a witch to curse him, but in the end they couldn't defeat him - they had to give him his lands back. Naturally, since the story has a happy ending, very few people now remember him at all :)
