Princess Maria Antonia of Naples and Sicily (died 1806)

Maria Antonia of Naples and Sicily was the youngest surviving daughter of Ferdinand, King of Naples and Sicily, and Maria Carolina of Austria. As the wife of the future Ferdinand VII of Spain, then heir apparent to the Spanish throne, she held the title of Princess of Asturias. It was rumoured that her mother-in-law, Maria Luisa of Parma caused her death, but there is no evidence to prove this.
