Re Littlefield surname- I know that a family of Littlefields were evacuated to Halifax just before the Channel Islands were evacuated in 1940, and never came back after the Liberation in 1945- I think they had connections with both Guernsey and Alderney and remember meeting Bill and his sister Muriel on their visits to Guernsey- Muriel was friends with my mother. There was also another brother called Norman.
