Maria Isabel Ana de Borbón

Princess Maria Isabel Ana of Naples and Sicily was the third daughter of Charles VII of Naples and III of Sicily and Maria Amalia of Saxony, who later became King Charles III and Queen Maria Amalia of Spain. She was the older sister of kings Charles IV of Spain and Ferdinand I of the Two Sicilies. She died before her father's accession to the Spanish throne, and thus never held the title of Infanta of Spain.
