On 12 October 1947, the Duchess married "Don" Luis Martínez de Irujo y Artázcoz (1919–1972), younger son of the Duke of Sotomayor and his wife Ana María de Artázcoz y Labayen (1892–1930), court lady of Queen Victoria Eugenia of Spain. The wedding in Spain, two years after the end of World War II, resisted the decline in frequency of very extravagant European weddings among high nobility and attracted the attention of the international media. "The New York Times" called it "the most expensive wedding of the world." It was reported that 20 million pesetas (equivalent to $10,000,000 rounded in 2015) was spent.
