Hi Scott,
My great Aunt, Lillian Lingham married Ray Maddieson - and I know my father (John Lingham) has a cousin called Peter who is one of the four Maddieson children, this would make your grandfather my second-cousin. So we are distant relations! He, along with my late grandmother Edna Lingham, has fond memories of holidays in Little Stone in the Maddiesons holiday camp and I myself have childhood memories of daytrips to the beach, and riding on the Greatstone miniature railway to Dungeness and back.
