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.[1]

One continuing male-line branches of the House of Luxembourg include the House of Salm. The later House of Limburg, Dukes of Limbourg, whose descendants became Dukes of Luxembourg and a royal dynasty in Germany, descend from the House of Ardennes-Luxembourg through the daughter of Frederick, Duke of Lower Lorraine.[2]

Children of Count Sigfried:

  • Thierry (d. 1075)
  • Henry, Count Palatine of Lorraine (d. 1095)
  • Poppon of Metz (d. 1103), Bishop of Metz
