In the early 19th century the Herwarth line died out. Schloss Hohenburg changed hands a number of times, belonging to the Zech family in 1807, the Kramer family in 1817 and the Taufkirchen family in 1833. In 1836 it and the accompanying large feudal estate were bought by Prince Carl of Leiningen (1804 - 1856), half-brother to Queen Victoria through his mother, Princess Victoria of Saxe-Coburg-Saalfeld, who remarried to Prince Edward, Duke of Kent and Strathearn after the death of her first husband, Prince Emich Carl of Leiningen. He had changes made to the exterior of the palace, redecorated several rooms, and converted the Baroque garden to a park in the English style. He was also an enthusiastic huntsman and developed an extensive hunting preserve at Lenggries. He built the Gothic Waldleiningen Castle in the Odenwald at the same time.
