Кристиан IX
Because so many monarchs descend from both Queen Victoria and King Christian IX of Denmark, the relationship between these two monarchs is of some interest. These monarchs were third cousins through their mutual descent from King George II of Great Britain. This relationship occurs twice because the maternal grandparents of King Christian IX of Denmark, Prince Charles of Hesse-Kassel (or Hesse-Cassel) (1744–1836) and Princess Louise of Denmark (1750–1831), were both children of daughters of King George II of Great Britain (1660–1727), and thus first cousins. Louise of Hesse-Kassel, wife of King Christian IX of Denmark, was a granddaughter of Prince Frederick of Hesse (1747–1837), the brother of the aforementioned Prince Charles of Hesse-Kassel.
