House of Ardenne–Luxembourg

The House of Luxembourg (or Luxembourg), also known as the House of Ardenne–Luxembourg in order to distinguish it from later families, were a Lotharingian noble family known from the tenth and eleventh centuries. They are one of the three main branches of the House of Ardenne, along with the House of Ardenne–Verdun, and the House of Ardenne–Bar.

All these Ardennes families descended from Cunigunda of France, a granddaughter of the West Frankish king Louis the Stammerer, and her husband Wigeric of Lotharingia. The Luxembourg branch descend from their son Sigfried, Count of the Ardennes.

One continuing male-line branches of the House of Luxembourg include the House of Salm.
