Viscountess Duncannon was Miss Mary Munn, daughter of Charles A. Munn and Mme. Jacques Allex. She was married this autumn to the First Secretary of the British Embassy. The service at the American Cathedral was followed by a reception at the Ritz. Her trousseau was made for her by Molyneux; from it, this grey moiré faille, Empire-waisted dress.
