The phenomenon of 'lost' villages was the result of enforced land clearance to make way for sheep pastures in the 14th Century, as well as more natural causes such as war, plague and migration of those seeking work elsewhere. It is estimated that there are seven to ten thousand lost villages and hamlets. One Cornelius Beningfield married Mary Griffin on the 8th January 1776 at St. Dunstan, Stepney, London.
