Stock Photo - Dec. 19, 1965 - An unusual photograph of Lady Mary Baillie-Hamilton reflected in the mirror top table in the drawing room of her home at Chelsea. She Will Attend The Queen On Coronation Day: Six beautiful girls whose ages range from 17 to 83 have been chosen by the Queen to be her Maids of Honour at the Coronation Service. Queen Victoria set the precedent when she was crowned. Maids of Honour instead of the usual Pages carried her train. The girls are being trained by Mary, Duchess of Devonshire, Mistress of the Robes to the Queen. She is showing them how to manage the Royal purple robe, which is 20 yards long and 21 inches wide. One of the girls chosen is 18-year-old Lady Mary Baillie-Hamilton, daughter of the Earl and Countess of Haddington and friend of both the Queen and of Princess Margaret. Lady Mary was a debutante in 1951 and her coming-out party was described as the most dazzling of the year. Her home is at Gordon in Scotland, but she is spending most of her time now at her pretty home in Tite Street, Chelsea where she is busy with Coronation year parties and preparing for her duties on the great day in Westminster Abbey.
