Overview
Juliane Sophie (18 February 1788, in Copenhagen – 9 May 1850, in Copenhagen) was a Princess of Denmark, the daughter of Frederick, Hereditary Prince of Denmark, who himself was a younger son of King Frederick V of Denmark in his second marriage to queen Juliana Maria of Braunschweig-Wolfenbüttel.
Family
Princess Juliane Sophie was the oldest daughter and second surviving child of Hereditary Prince Frederick and his wife Duchess Sophia Frederica of Mecklenburg-Schwerin, daughter of Duke Louis of Mecklenburg-Schwerin and Princess Charlotte Sophie of Saxe-Coburg-Saalfeld. Her siblings included the future Christian VIII of Denmark.
Prince Frederick and Princess Sophia Frederica did not have any surviving children in the first 10 years of marriage, but eventually they had four children.
The actual paternity of Princess Juliane and her three siblings has been debated, and it is widely believed that the father of Sophia Frederica's children was Prince Frederick's adjutant, Frederik von Blücher.
