Siegfried of Luxembourg

Siegfried or Sigefroy (c.922–28 Oct 998) is considered the first count of Luxembourg. He was actually count in the Moselgau and the Ardennes. He was also the advocate of the abbeys of Saint-Maximin de Trêves and Saint-Willibrod d'Echternach. He was a son of the Count Palatine Wigeric of Lotharingia and Cunigunda. He is the founder of the House of Luxembourg, a cadet branch of the House of Ardennes.

He had possessions from his father in Upper Lorraine. At the centre of his dominions he constructed the fortress of Luxembourg in 963. A town soon grew up around the castle. Though he used the title of count, the title "count of Luxembourg" was only applied to William some 150 years later.

Around 950, he married Hedwig (937–992), daughter of Eberhard IV of Nordgau. They had the following issue:

*Henry I of Luxembourg
*Siegfried, cited in 985
*Frederick I, Count of Salm and Luxembourg, married Ermentrude of Gleiberg, daughter of Heribert I, Count of Gleiberg and Ermentrud (Imizi).
