Her Wikipedia article is here. She was the daughter of Amelie Auguste of Bavaria. She married Archduke Karl Ludwig in 1856 and had a happy marriage cut very short when she succumbed to typhoid in 1858. She bore no children, but Karl Ludwig would marry two more times to Princess Maria Annunciata of the Two Sicilies and then Infanta Maria Teresa of Portugal. The assassination of one of Karl Ludwig’s children, Franz Ferdinand, started World War I and making the twentieth century the most violent ever. Franz Ferdinand married Sophie Chotek.
