Ingolf

Count Ingolf of Rosenborg (born 17 February 1940) is a Danish count and former prince. Born Prince Ingolf of Denmark (Danish: Prins Ingolf Christian Frederik Knud Harald Gorm Gustav Viggo Valdemar Aage til Danmark), he appeared likely to some day become king until the constitution was changed in 1953 to allow females to inherit the crown, placing his branch of the dynasty behind that of his first cousin Princess Margrethe and her two younger sisters. He later gave up his princely rank and his rights to the throne in order to marry a commoner.
