Beaufort-Spontin

The family is descended from the Counts of Beaufort, who held land near Huy in the early 11th century. The original family split into several branches, including those of Spontin and of Vêves (the present Counts of Liedekerke-Beaufort descend from the latter). The branch of Beaufort-Spontin settled in Freÿr in the early 15th century.[5]

In 1783, the 1st Duke of Beaufort-Spontin married María Leopoldina Álvarez de Toledo y Salm-Salm, 10th Marchioness of Almenara, in Paris. She was the daughter of the 12th Duke of Infantado and of Princess María Ana Victoria of Salm-Salm, a grand-daughter of the Prince of Löwenstein-Wertheim-Rochefort.[6] This made Frederic August a brother-in-law of Pedro de Alcántara Álvarez de Toledo, who was Prime Minister of Spain. The second child of Beaufort and María Leopoldina would marry the 10th Duke de Osuna, and their children would eventually become the 11th and 12th Dukes of Osuna.

• Friedrich Christian, 7th Duke of Beaufort-Spontin (born 1944) is the son of the sixth duke by his 1943 marriage to Christiane Steinheuer. Born at Petschau, he is a physician specializing in nuclear medicine, formerly a professor at Graz University, and lives in Steiermark, Austria. As neither he nor his brother, Count Christian de Beaufort-Spontin (born 1947), has sons by their marriages, the ducal and princely titles have no heirs in the next generation.[1]
