Her parentage and first marriage are indicated by the charter dated to [915] under which Charles III “le Simple” King of the West Franks donated the abbeys of Hastières and Saint-Rombaut to Liège Saint-Lambert, granting the enjoyment for life to "comes Windricus...uxoris eius...Cunegundis et unius filiorum ipsorum...nostri nepotis Adelberonis". Her first and second marriages are confirmed by the Vita Iohannis Gorziensis which names "episcopo…Adalberone" (her son by her first husband) and "vitrico…eius Richizone" (her second husband). Her parentage is confirmed more specifically because the mother of Siegfried Count of Luxembourg is named "Cynigund", daughter of "Irmindrud" daughter of Louis II "le Bègue" King of the West Franks, in an 11th century genealogy which traces the ancestry of Siegfried's daughter Empress Kunigund. The family relationship between Count Siegfried and the descendants of Wigerich [III] is confirmed by a reference in one of Gerbert's letters to Siegfried being patruus of Wigerich's grandson Gozelo. However, Siegfried’s birth is estimated to [930/40] which indicates that he could not have been the son either of Wigerich or Cunigonde's second husband Richwin. The only explanation which is consistent with all the sources is that Cunigonde married for a third time after the death of her second husband and that she was the mother of Siegfried by her third marriage. This necessitates a somewhat broad interpretation of “patruus” in Gerbert. The identity of Cunigonde´s supposed third husband, the father of Siegfried, has not been ascertained. The name of Siegfried´s oldest son suggests that he may have been called Heinrich. 1
