Domesday Book
Domesday Book held at The National Archives, is the record of the great survey of much of England and parts of Wales completed in 1086. The survey was executed for William I of England (William the Conqueror): "While spending the Christmas of 1085 in Gloucester, William had deep speech with his counsellors and sent men all over England to each shire to find out what or how much each landholder had in land and livestock, and what it was worth" (Anglo-Saxon Chronicle).
