Prince Erik, Count of Rosenborg

Prince Erik, Count of Rosenborg (Erik Frederik Christian Alexander zu Schleswig-Holstein-Sonderburg-Glücksburg; 8 November 1890 – 10 September 1950) was a Danish royal family member. He was born at Copenhagen, the 3rd son of Prince Valdemar of Denmark and Princess Marie of Orléans.

Early life
Prince Erik was born on 8 November 1890, in the Yellow Palace, an 18th-century town house at 18 Amaliegade, immediately adjacent to the Amalienborg Palace in Copenhagen. The third child of Prince Valdemar of Denmark and his wife Princess Marie of Orléans, his father was a younger son of King Christian IX of Denmark and Louise of Hesse-Kassel, and his mother was the eldest daughter of Prince Robert, Duke of Chartres and Princess Françoise of Orléans. His parents' marriage was reputed to be a political match.

Prince Erik was christened 10 days after his birth and his godparents were his paternal grandparents, King Christian IX and Queen Louise of Denmark; his paternal uncle and aunt, Tsar Alexander III of Russia and Empress Maria Feodorovna; and his paternal uncle and aunt, Crown Prince Frederik and Crown Princess Louise of Denmark.

Later created Count of Rosenborg, Erik inherited the family estates.

Marriage and issue
As was then customary with Danish royalty, Erik renounced his rights to the throne when he chose to take a commoner as wife, marrying in Ottawa, Ontario, on 11 February 1924 Lois Frances Booth (Ottawa, Ontario, 2 August 1897 – Copenhagen, 26 February 1941).
