As you may have read in your newspaper, William the Conqueror's Doomsday Book is now online and searchable at National Archives, http://www.nationalarchives.gov.uk/domesday/ More information about the Doomsday Book can be had at this website. In the search window I entered "Davenport" and got results. (There is a small fee to download further documentation.) Have fun. Don (Davenport) Crawford
