Count of Merenberg

Count of Merenberg (German: Graf von Merenberg) is a hereditary title of nobility that was bestowed in 1868 by the reigning Prince of Waldeck and Pyrmont, George Victor, upon the morganatic wife and male-line descendants of Prince Nikolaus Wilhelm of Nassau (1832–1905), who married Natalia Alexandrovna Pushkina (1836–1913), former wife of Russian general Mikhail Leontievich von Dubelt.

As such, she was not legally permitted to share her husband's princely title or rank, even though his family had ceased to be hereditary rulers when the kingdom of Prussia annexed Nassau.

Through Pushkin, Natalia descended from Peter the Great's African protégé, Abram Petrovich Gannibal.

However, his morganatic birth was deemed insurmountable, despite the fact that he had married a daughter of Tsar Alexander II of Russia.

In 1907, William IV, obtained passage of a law in Luxembourg confirming the exclusion of the Merenbergs from succession to the grand ducal throne.
