  Research Notes:

The parentage of the wife of Graf Friedrich is suggested by the Vita Adelheidis which names "Irminthrudis, Alverad [et] Berthrada" as the three sisters of Adelheid, and daughters of "Megengoz" and his wife, specifying that Irminthrudis was grandmother of [three of the sons of Graf Friedrich...] "Heinrici magnifici ducis et Adhelberonis Metensis episcopi, Friderici ducis". The possibility of this person´s earlier otherwise unrecorded marriage is suggested by the Genealogia Welforum which names [this person´s daughter] "Salice---de Glizperch Imizam nomine, Heinrici Noricorum ducis sororem et Friderici ducis Lotharingorum et Alberonis Metensis episcopi" as wife of Welf [II] Graf von Altdorf... The reference to “Glizperch” represents the earliest indication of a relationship between the Luxembourg family and the Grafen von Gleiberg... One possibility is that the wife of Graf Friedrich was heiress of Gleiberg. However, Irmtrud/Imiza is the only one of the siblings shown below in relation to whom a reference to Gleiberg has been found. This raises the interesting possibility that Irmtrud/Imiza, while sharing the same mother as the three brothers named in the Genealogia Welforum, may have been born from a different father who presumably held Gleiberg. It should be emphasised that this suggestion is highly speculative. Another indication of a Gleiberg/Luxembourg family connection is provided by Bernold´s Chronicon which records in 1059 that “Fridericus et fratres eius de Glichberga” rebelled against “Heinrico regi”. It is not known which of Friedrich´s brothers may have been “von Gleiberg”. Another possible indication of the family origin of the wife of Graf Friedrich is provided by the Chronicle of Alberic de Trois-Fontaines which records that "comes Letardus de Longui pater Manegaudi et Gislebertus comes de Luscelenburch" were "nepotes" of Emperor Konrad II. The precise family relationships between these three persons have not been traced, but it is possible that Giselbert was related to the emperor through his mother´s family, which had many Franconian connections. 1

  Marriage Information:

Irmentrude married Frédéric I DE LUXEMBOURG Count in Moselgau, son of Siegfried VON LUXEMBURG Count of Luxemburg and Hedwig VON NORDGAU Countess in Nordgau. (Cte Frédéric I DE LUXEMBOURG died on 6 Oct 1019.)
