of Imperial Princes (Reichsfürstenrat or Fürstenbank) in the Imperial Diet in 1726. Upon his admission he had to promise to purchase some immediate territory on the first occasion, since all of the family's possessions had no such status as they were located within the Archduchy of Austria. Finally a splinter share of the immediate County of Limpurg was inherited by Johann Josef Wilhelm's wife Countess Juliane Dorothea von Limpurg-Gaildorf, a territory around its residence Gaildorf, Swabia, that had been divided between a large number of heirs when its former rulers, the Counts Schenk von Limpurg extinguished in 1713, leaving ten daughters. With this splinter share, the acquisition of a territory with Imperial Immediacy was fulfilled and the head of the family became a hereditary member of the Swabian count's bench. The county of Limpurg was mediatized in 1806 and became part of the Kingdom of Württemberg. The Mediatized Houses however kept their princely status. The elder branch extinguished with count Degenhard in 1965, and his only daughter Leonora inherited Steyersberg castle; it is now owned by her son Dr Paul Miller. The headship of the house went to count Ernst Gundaccar (b. 1946) of the younger branch, formerly residing at Liblín (Czech Republic). His mother, the heiress of Schloss Frohsdorf, was princess Blanca Massimo, daughter of Prince Fabrizio Massimo and Princess Beatrix of Borbon-Spain, herself a daughter of Carlos, Duke of Madrid. Frohsdorf castle was sold in 1941, but the estate is still owned by count Ernst Gundaccar who has two sons. Schloss Stubenberg in Styria was bought in 1815 and given to the Catholic Church in 1925 as a monastery, when two daughters took the veil. The third branch resided at Reitenau castle near Stambach (1602-1822) and at Gornja Radgona Castle (1789-1914). In 1694 they purchased Altschielleiten castle at Stubenberg, Styria, where the new Schielleiten Palace was built from 1730. When this branch extinguished in 1906, the palace was inherited by the Marchese Tacoli family.
