TORLONIA (Duc), a name mentioned, in December, 1829, by the Baron Frederic de Nucingen, as that of one of his friends, and pronounced by him "Dorlonia." The duke had ordered a magnificent carpet, the price of which he considered exorbitant, but the baron bought it for Esther van Gobseck's "leedle balace" on the rue Saint-Georges. The Duc Torlonia belonged to the famous family of Rome, that was so hospitable to strangers, and was of French origin. The original name was Tourlogne. [Scenes from a Courtesan's Life.]
