BRANDON (Lady Marie-Augusta), mother of Louis and Marie Gaston, children born out of wedlock. Together with the Vicomtesse de Beauseant she assisted, in company with Colonel Franchessini, probably her lover, at the famous ball on the morning following which the duped mistress of D'Ajuda-Pinto secretly left Paris. [The Member for Arcis.] In 1820, while living with her two children in seclusion at La Grenadiere, in the neighborhood of Tours, she saw Felix de Vandenesse, at the time when Mme. de Mortsauf died, and charged him with a pressing message to Lady Arabelle Dudley. [The Lily of the Valley.] She died, aged thirty-six, during the Restoration, in the house at La Grenadiere, and was buried in the Saint-Cyr Cemetery. Her husband, Lord Brandon, who had abandoned her, lived in London, Brandon Square, Hyde Park, at this time. In Touraine Lady Brandon was known only by the assumed name of Mme. Willemsens.
