Death and succession The duchess died under somewhat mysterious circumstances in July 1802 at the age of 40. Although her death was ostensibly due to tuberculosis and a fever, more colorful scenarios have been suggested over the years, among them a theory that she was poisoned (this theory was dramatized in the film The Naked Maja). She had no biological children, although she did have an adoptive daughter, known as María de la Luz. After her death, the Alba ducal title passed to a relative, Carlos Miguel Fitz-James Stuart (1794–1835), who became the 14th Duke of Alba.
