Marie’s father, Grand Duke Leopold, descended from a morganatic branch of the Baden family (his mother was Louise Caroline of Hochberg, a noblewoman) and thus did not have rights to a princely status or the sovereign rights of the House of Zähringen of Baden. However, in 1830 he ascended to the throne of the Grand Duchy of Baden after the main male line of his family died out. Leopold was considered the first German ruler who held in his country's liberal reforms. Her mother, Sophie Wilhelmine of Sweden, was a daughter of King Gustav IV Adolf of Sweden and Frederica of Baden.
Princess Alberta of Leiningen (23 July 1863 [2] – 30 August 1901).
