The House of Aspremont-Lynden is the name of an important Belgian noble family, which might have originated from the House of Lynden, part of the Dutch nobility. Due to their properties and intermarriages, the family also became part of the German nobility.
The proven line starts with Thierry van Lynden (married 1520, died 1566), as the first mentioned member of this family. In 1676 and 1677 nobility decrees of Emperor Leopold I followed for descendants of this family, with the title of Count. Ferdinand von Aspremont-Lynden was the reigning Count of Reckheim and had the Aspremont-Lynden Castle constructed. Since Ferdinand Gobert d'Aspremont Lynden several descendants fought in Austrian service.
By collective Royal Decree of 20 February 1816, Joseph-Ferdinand von Aspremont Lynden (1784–1843) was appointed to the (modern) Knighthood of Namur with the title of Count in Belgium. In the centuries that followed, members held administrative positions at the local, provincial, and national levels. In the 20th century, some members served science.
Christophe Butkens (1590-1650) wrote in his Annales généalogiques de la maison de Lynden that Thierry van Lynden descended from the old noble Van Lynden family from the Northern Netherlands, but this thesis has proved to be untenable. Still later they usurped the name d'Aspremont, as if they descended from the old noble family of that name, but this also turned out to be unproven.
