Flakebridge

My mother died on 13 June 2011 aged 87 years old. Her name was Margaret Elfin Gunn (nee Simpson). Her date of birth was 03 October 1923 and she was born in Flakebridge, Dufton. She was the first of 15 children in the Simpson family, 10 girls and 5 boys. Her father was Thomas Frederick Simpson (Farm Laborer) and mother was Edith Annie Simpson (formerly Barker). I believe that she was in service. My mother's name Elfin was after a member of the family that she worked for. My Grandad eventually had his own farm, Sandford Hall at Sandford. If anyone has any further information or could point me in the right direction of the house that my mother may have been born in could you please let me know, my email is ycr62@aol.co.uk. I would love to go and see it if it is still there. Many thanks.
