The Duchess of Alba, known not only for being Spain’s wealthiest aristocrat, but also as the world’s most titled noble, has died at age 88. Maria del Rosario Cayetana Fitz-James Stuart y Silva had an estimated net worth of $3.5 billion, married three times, was cousins with Winston Churchill, and shared toys growing up with Queen Elizabeth II. She held six dukedoms. The duchess died at her Duenas Palace in Seville on Wednesday from pneumonia.
