The Toerring-Jettenbach family are a Mediatized Family from the Second Section of the Almanach de Gotha...not royal per se, but almost royal in fact. They were a family that First Section families could marry into without incurring into marriage inequality.
Karl Theodor, Toto, was not only the Head of House, but also the son of a Bavarian princess and hence a nephew of Queen Elisabeth of the Belgians, Princess Rupprecht of Bavaria and the Duchess of Urach. His mother was a niece of Empress Elisabeth of Austria, Queen Marie of the Two Sicilies, the Hereditary Princess of Thurn und Taxis and the Duchess d'Alencon, among others.
Toto Toerring was a first cousin of King Leopold III of the Belgians, the Duke or Urach and of Duke Albrecht of Bavaria (Head of House) and this is only through the Bavarian side of the family. If one looks at the Braganza connection the list ofhis relations is simply impressive!
