GRANDLIEU (Duc Ferdinand de), born about 1773; may have descended from the Comtesse de Grandlieu who lived early in the seventeenth century, and consequently connected with the old and worthy nobility of the Duchy of Brittany whose device was "Caveo non timeo." At the end of the eighteenth and the first half of the nineteenth centuries, Ferdinand de Grandlieu was the head of the elder branch, wealthy and ducal, of the house of Grandlieu. Under the Consulate and the Empire his high and assured rank enabled him to intercede with Talleyrand in behalf of M. d'Hauteserre and M. de Simeuse, compromised in the fictitious abduction of Malin de Gondreville. Grandlieu by his marriage with an Ajuda of the elder branch, connected with the Barganzas and of Portuguese descent, had several daughters, the eldest of whom assumed the veil in 1822. His other daughters were Clotilde-Frederique, born in 1802; Josephine the third; Sabine born in 1809; Marie-Athenais, born about 1820. An uncle by marriage of Mme. de Langeais, he had at Paris, in Faubourg Saint-Germain, a hotel where, during the reign of Louis XVIII., the Princesse de Blamont-Chauvry, the Vidame de Pamiers and the Duc de Navarreins assembled to consider a startling escapade of Antoinette de Langeais. At least ten years later Grandlieu availed himself of his intimate friend Henri de Chaulieu and also of Corentin—Saint-Denis—in order to stay the suit against Lucien de Rubempre which was about to compromise his daughter Clotilde-Frederique.
