Lady Massereene, formerly Jean Barbara Ainsworth, pictured in costume with Patrick Shaw Stewart at a masque arranged by Lord and Lady Desborough at their home, Taplow Court, in January 1912. Shaw Stewart was an Eton College and Oxford scholar and poet of the Edwardian era who died on active service as a battalion commander in the British Royal Naval Division during the First World War. He is best remembered today for his poem Achilles in the Trench, one of the best-known war poems of the First World War.
