Duke Alexander of Württemberg was the son of Duke Louis of Württemberg and the nephew of Empress Maria Feodorovna of Russia (see lots 122 and 199). In 1835, he married morganatically a Hungarian countess, Claudine Rhédey von Kis-Rhéde. The same year she was created Countess von Hohenstein in her own right by Emperor Ferdinand I of Austria. She was killed aged 24, when thrown from a bolting horse and trampled by the Austrian cavalry. Alexander and Claudine had three children: Claudine, Francis and Amalie. Their son Count Francis von Hohenstein, later granted the title of Prince of Teck, married Mary Adelaide, daughter of Duke Adolphus of Cambridge. They had four children, including a daughter, Mary of Teck, who married George Duke of York, later King George V.
