There is a mistake in the previous posts, who arrived to Argentina where baron Franz Ferdinand von Wuthenau and his wife Elinor Bromberg, they had four children Marie Antoinette born in Germany before WW2, and Francisco Fernando born in Argentina plus Elisalex and Paulette. The four brothers had family here in Argentina, Marie Antoinette is countess Sagramoso, and he had a son Lionello and a daughter Domitila, her brother has a large family and her other two sisters as well. Their grandmother Chotek never visited Argentina, was one of the sisters of Sophie Countess Chotek, after her wedding was the Duchess of Hohenberg. Their cousin Georg Herzog (Duke) von Hohenberg lives in Austria, he was a former Austrian diplomat, and he used to visit Argentine quite often. They are the ones related to the Kinsky family, their cousin Franz Ulrich passed away in Buenos Aires some five years ago, he had just one son, Charles who lives in London with his wife Dolores and family, he is the current head of the Kinsky family as "Reich Fürst" or head of the Princely Family of Kinsky.
