<Li> Jump up ^ Albert II had an older brother, Baudouin, who was king of Belgium as well . </Li> <Li> Jump up ^ Michael's wife, Queen Anne of Romania, is also descended from Christian IX through Prince Valdemar of Denmark . </Li> <Li> Jump up ^ Constantine II's wife, Queen Anne - Marie of Greece, is Margrethe II's younger sister . </Li> <P> 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, Landgrave 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 . It is also interesting to note that 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 Landgrave Charles of Hesse - Kassel . </P>
