グリュックスブルク家
Princess Ingrid Alexandra of Norway (born 21 January 2004) is the elder child of Crown Prince Haakon and Crown Princess Mette-Marit. She is second in line to succeed her grandfather King Harald V. She has a younger brother, Prince Sverre Magnus, whom she ranks above in the line of succession due to the implementation of absolute primogeniture in 1990. A member of the House of Glücksburg, she is expected to become the country's second female monarch, after the 15th-century Queen Margaret.
