There's an very interesting and entertaining article in today's Guardian newspaper about the Robin Hood legend. Among the several experts the journalist talks to is David Crook, editor of the Thoroton Society Record Series publications and former assistant keeper at The National Archives. David is currently writing a book about Robin Hood and thinks he has traced him to Yorkshire in 1225 (not music to the ears of Nottinghamshire's tourist industry!). He has discovered a character called Robert Hod (described as 'an outlaw and evildoer of our land') who may be the same person as Robert of Wetherby who was hunted down by the Sheriff of Nottingham and his men.
Fascinating stuff so I recommend you take a look at the whole article:
