Marie Caroline, nicknamed Lina, was born in Vienna on April 26th 1822. She was the favourite granddaughter of her maternal grandfather Emperor Franz I. of Austria. In 1832, Franz gave the painter Johann Ender the order to create a portrait of his three favourite grandchildren Lina, Franz Joseph and Franz Reichstadt.
Lina married Henri d'Aumale, Prince d'Orléans in Naples on November 25th 1844. They had four sons: Louis Philippe (1845-1866), Henri Léopold (1847-1847), François Paul (1852-1852) and François Louis (1854-1872) who all died quite young. Lina also had miscarriages in 1849, 1861 and 1864.
When Sophie en Bavière married Ferdinand d'Alencon in 1868 and went with him into the English exile, she got to know Lina and Uncle Aumale. Sophie and the couple spent much time together and when Lina died only one year later, on December 6th 1869, aged 47, Sophie suffered a lot.
