United Kingdom of the Netherlands Kingdom of Belgium The House of Beaufort-Spontin is a noble family which held prominent posts under the Holy Roman Emperors in the Austrian Netherlands, their family seat having originally been in Namur.

[4][5] 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).

[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.
