Caroline married on 2 December 1786 in
Biebrich to
Landgrave Frederick of Hesse-Kassel, youngest child of
Frederick II, Landgrave of Hesse-Kassel and
Princess Mary of Great Britain, daughter of
George II of Great Britain. The Landgrave and Prince Frederik was born a German (Hessian) aristocrat, a cadet son of a Landesfürstliche house, but had lived since his youth in Denmark, as had his two elder brothers. Frederik's two elder brothers married daughters of the deceased King of Norway and Denmark. However, there was no Danish royal daughter left to marry the youngest boy, Frederik, so he married a cousin of the Duke of Augustenborg, being Caroline of Nassau. Frederik was an infantry general in Danish service. They had eight children: •
William (24 December 1787 – 5 September 1867), married
Louise Charlotte of Denmark (1789–1864) and was the father of
Louise of Hesse-Kassel (wife of
Christian IX of Denmark). • Karl Friedrich (9 March 1789 – 10 September 1802) • Friedrich Wilhelm (24 April 1790 – 25 October 1876) • Ludwig Karl (12 November 1791 – 12 May 1800) • Georg Karl (14 January 1793 – 4 March 1881) • Luise Karoline Marie Friederike (9 April 1794 – 16 March 1881) •
Marie Wilhelmine Friederike (21 January 1796 – 30 December 1880), married
Georg, Grand Duke of Mecklenburg-Strelitz (1779–1860) •
Augusta Wilhelmine Luise (25 July 1797 – 6 April 1889), married
