Prince Frederick Augustus of Anhalt-Dessau

Frederick was born in Dessau on 23 September 1799 as the fourth (but third surviving son) of Frederick, Hereditary Prince of Anhalt-Dessau, by his wife Landgravine Amalie of Hesse-Homburg, daughter of Frederick V, Landgrave of Hesse-Homburg.

In Rumpenheim Palace in Offenbach am Main on 11 September 1832, Frederick Augustus married Princess Marie Luise Charlotte of Hesse-Kassel (b. Copenhagen, 9 May 1814 - d.

Marie was an older sister of the later Queen Louise, wife of King Christian IX of Denmark.

Frederick and Marie had three daughters:[1][2]

1. Adelaide Marie (b. Dessau, 25 December 1833 - d. Schloss Königstein, 24 November 1916), married on 23 April 1851 to Adolphe, last Duke of Nassau and first Grand Duke of Luxembourg. The current Grand Duke of Luxembourg, Henri, is her direct descendant.
