Princess Sibylla of Saxe-Coburg and Gotha

Princess Sibylla of Saxe-Coburg and Gotha (18 January 1908 – 28 November 1972) was the mother of the current King of Sweden, Carl XVI Gustaf. A member of the House of Saxe-Coburg and Gotha, Sibylla became a Swedish princess by marrying Prince Gustaf Adolf, Duke of Västerbotten. On 19 October in Coburg, Sibylla married her second cousin Prince Gustaf Adolf of Sweden, Duke of Västerbotten, in a civil ceremony, followed by a church wedding the day after. Gustaf Adolf was the eldest son of Crown Prince Gustav Adolf of Sweden (later Gustaf VI Adolf) and Princess Margaret of Connaught, a granddaughter of Queen Victoria. Both Sibylla and Gustaf Adolf were great-grandchildren of Queen Victoria. Sibylla never became Crown Princess herself since her husband died before his grandfather (King Gustav V).
