Leopold was one of the four sons and nine children of Queen Victoria and her cousin, Prince Albert of Saxe-Coburg, whom were all born in the 18 years following their wedding in 1840. Along with his sisters, Alice and Beatrice, Leopold inherited the disease haemophilia from his mother. Leopold himself eventually died from the disease. (PROSE: The Time Traveller's Almanac)
