"Sigfried (or Siegfried) (c. 922 – 28 October 998) was count of the Ardennes and the first person to rule Luxembourg. He was an advocate of the abbeys of St. Maximin in Trier and Saint Willibrord in Echternach. His mother was Cunigunde who was a granddaughter of Louis II, king of France. Cunigunde had at least two husbands but Sigfried´s father was most likely Count Palatine Wigeric of Lotharingia.
Sigfried is the ancestor of the first House of Luxembourg, the so-called House of Ardenne-Luxembourg. In turn, Sigfried´s family is one branch of the larger House of Ardennes, which includes descendants of his mother Cunigunde." - (en.wikipedia.org 08.09.2020)
