 Cyril Beaumont died in 1973, becoming the fifth child Dame Sibyl outlived. Early next year, the 90-year-old gave her approval for the stage presentation of William Douglas-Home's play The Dame of Sark, inspired by her experiences in the Second World War. She looked forward to meeting Celia Johnson, who was to play the title role, but died suddenly at the Seigneurie of a heart attack on 14 July 1974.
