Read the passage from "Children of the Wartime Evacuation.” In January 1941, Sheila Shear and her sister were evacuated from east London to the Chilterns and billeted with a bachelor called Harry Mayo. They came from very different backgrounds – the Shears were Jewish, he was Christian – but an affectionate bond developed between them. Weekly visits and holidays with Uncle Harry, as they came to know him, continued long after the war had ended.
