Princess Maria Immacolata of Bourbon-Two Sicilies (1844–1899)

Maria Immaculata was modest and reserved growing up and was jokingly called by her father "Petitta." Her mother, Maria Theresa, detested parties and court life and instead, she devoted herself to the care of her children and sewing.

After the fall of the Kingdom of the Two Sicilies during the Expedition of the Thousand, the royal family fled to Rome where they resided at the Quirinal Palace at the invitation of the Pope Pius IX.

Maria Immaculata married Archduke Karl Salvator of Austria, fifth child and second-eldest son of Leopold II, Grand Duke of Tuscany and his wife Princess Maria Antonia of the Two Sicilies, on 19 September 1861 in Rome.

The family spent two or three summers in Baden, so that Karl Salvator could go to the sulfur baths.^[1] Both Maria and Karl Salvator became popular with local citizens.^[1] In late September 1878, after Maria gave birth to a daughter in Baden, Emperor Ferdinand himself visited to attend the christening of Maria Immaculata Raineria; the archduchess was congratulated with a torchlight procession and presented a large bouquet of flowers by mayor of Baden Count Christalnigg.^[1]

Maria Immaculata was known for her beauty. She was included in Empress Elisabeth of Austria's photo album of beautiful women. Because Maria Immaculata's husband gave her a pearl necklace each time she bore another child, Empress Elisabeth mockingly nicknamed the family "The Pearl Divers". Eventually, Empress Elisabeth's youngest daughter Archduchess Marie Valerie married Maria Immaculata's son Franz Salvator.
