Duchess Elisabeth Alexandrine Constance of Württemberg (27 February 1802 in Würzau, Courland Governorate – 5 December 1864, in Karlsruhe) was a daughter of Duke Louis of Württemberg and Princess Henriette of Nassau-Weilburg.

Margrave Wilhelm of Baden (8 April 1792 in Karlsruhe – 11 October 1859 in Karlsruhe) was the second son of Karl Friedrich, Grand Duke of Baden and his second wife, Luise Karoline, Baroness Geyer von Geyersberg (26 May 1768 – 23 July 1820), the daughter of Lt. Col. Baron Ludwig Heinrich Philipp Geyer von Geyersberg and his wife, Countess Maximiliana Christiane von Sponeck. Because his marriage to Luise was considered by the House of Baden as morganatic, Wilhelm, for a time, had no succession rights to the Grand Duchy. For most of his life he was a part of the military, notably achieving the rank of colonel and commanding the Baden brigade in the Grande Armée during the French invasion of Russia.
