Notes:

Siegfried (or Sigefroy) (c. 922 - 28 October 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 is speculated to be the son of Wigeric of Lotharingia, Count Palatine 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 of Nordgau (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).
Dietrich, bishop of Metz
Adalberon, canon of Trier
Gislebert (d.1004), count in the Moselgau
Cunigunda, married Henry II, Holy Roman Emperor
Eve, married Gerard, Count of Metz
Ermentrude, abbess
Luitgarde, married Arnulf, Count of Holland
a daughter, married Thietmar

Siegfried married Hedwig of Nordgau Abt 950. Hedwig was born Abt 922; died 13 Dec 992. [Group Sheet]

Notes:

Hedwig of Nordgau (circa 922 - after 993) was the wife of Siegfried of Luxembourg, first count of Luxembourg and founder of the country. They were married circa 950. She was of Saxon origin but her parentage is not known for sure. Some sources list her as the daughter of count Eberhard IV of Nordgau and Luitgard of Lotharingia. Others claim that she was connected to the family of Otto I, Holy Roman Emperor. Described as "saintly" herself, Hedwig of Nordgau was the mother of Saint Cunigunde of Luxembourg, the sixth of eleven children from her marriage to Siegfried.

Children

Hedwig of Nordgau's children included:

Henry, count of Luxemburg
Adalbert, archbishop of Trier
Luitgard, married Arnulf, Count of Holland
Eva, married count Gerard of Elzass
Cunigunde, married Henry II, Holy Roman Emperor
Dietrich, bishop of Metz
Frederik, father of the later counts Henry II and Giselbert
