Princess_Maria_Antonia_of_Naples_and_Sicily

Maria Antonia of Naples and Sicily (14 December 1784 – 21 May 1806) 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 is alleged that her mother-in-law, Maria Luisa of Parma, poisoned her, causing her death, but there is no evidence to prove this.
