Giselbert of Luxembourg

Giselbert of Luxembourg (c. 1007 – 14 August 1059) was Count of Salm and of Longwy, then Count of Luxemburg from 1047 to 1059. He was a son of Frederick of Luxembourg,^[1] count of Moselgau, and perhaps of Ermentrude of Gleiberg.

At first count of Salm and of Longwy, on his brother Henry II's death he inherited the County of Luxembourg,^[2] as well as providing the income for the abbeys of Saint-Maximin in Trier and Saint-Willibrord in Echternach. He got into an argument with the Archbishop of Trier Poppon as to the abbaye Saint-Maximin, which was arbitrated by his brother Adalbero III, bishop of Metz.

In 1050, since the population of the town of Luxembourg had risen considerably, he expanded the city by building a new fortified wall around it.

By an unknown wife, he had:

• Conrad I, Count of Luxembourg^[3] († 1086)
• Hermann of Salm († 1088), count of Salm, founder of the House of Salm
• daughter, married Thierry of Amensleben
• daughter, married Kuno, count of Oltingen
• Adalbéron († 1097 at Antioch), canon at Metz
• Jutta, married Udo of Limbourg
• Rudolph, abbot of Altmünster Abbey^[3]
