Some really worthwhile websites

Masonic Great War Project

United Grand Lodge of England The main site for freemasonry in England offers insight into the organisation. It includes information on the Museum & Library, the source for much masonic history, and through which tours of the building including the Masonic 1914-18 memorial can be organised.   

Battlefield History TV  A highly professional delivery of history by battlefield experts

The Battlefield Guide   Frank Togood is simply one of the most talented brand designers, an expert on aspects of the Battle of Waterloo and a good friend. 

Commonwealth War Graves Commission  Probably the starting point for any general research.
