Interesting in this is that Mathilde Baroness von dem Bussche-Haddenhausen is related to the grandmother of Prince Willem-Alexander (Gösta von Amsberg née Baroness von dem Bussche-Haddenhausen).
A second interesting connection is that the 10th Fürst Kinsky went to Argentina when the Nazis and then the Communists seized Czechoslovakia (where the bulk of their properties was). It was there where the Fürst married Mathilde Baroness von dem Bussche-Haddenhausen, her mother was Maria Eleonore Martinez de Hoz.
When we think of Argentina, we of course think about Máxima. Her father Jorge was a minister in the Videla regime. His department felt under the jurisdiction of the super-department of Economy, led by José Alfredo Martínez de Hoz, a colleague of Jorge Zorreguieta in the Videla Cabinet and still a family friend.
