Princess Victoria of Hesse and by Rhine (b. 1863)
Princess Victoria Alberta Elizabeth Mathilde Marie of Hesse and by Rhine (5 April 1863 – 24 September 1950), later Victoria Mountbatten, Marchioness of Milford Haven, was the eldest daughter of Louis IV, Grand Duke of Hesse and by Rhine, and Princess Alice, daughter of Queen Victoria of the United Kingdom and Prince Albert of Saxe-Coburg and Gotha.
Born in Windsor Castle in the presence of her grandmother, Princess Victoria was raised in Germany and England. Her mother died while Victoria's brother and sisters were still young, which placed her in an early position of responsibility over her siblings. Over her father's disapproval, she married his morganatic first cousin Prince Louis of Battenberg, an officer in the United Kingdom's Royal Navy, and lived most of her married life in various parts of Europe at her husband's naval posts and visiting her many royal relations. She was perceived by her family as liberal in outlook, straightforward, practical and bright.
During World War I, she and her husband abandoned their German titles and adopted the surname of Mountbatten, which was an English translation of the German "Battenberg". Two of her sisters—Elisabeth and Alix, who had married into the Russian imperial family—were killed by communist revolutionaries. She was the mother of Queen Louise of Sweden and the British statesman and Royal Navy officer Louis Mountbatten, and the maternal grandmother of Prince Philip, Duke of Edinburgh, consort of Queen Elizabeth II.
