Gertrud Etichonid von Egisheim was born circa 995 to Hugo IV. von Egisheim (970-1047) and Heilwig von Dagsburg (?-?) and died 21 July 1077 of unspecified causes. She married Liudolf von Braunschweig (c1005-1038) .
Genealogie Mittelalter argues that she may be a daughter of Hugo IV. von Egisheim (970-1047), Aarnout van Holland (951-993), Ekbert Billung (935-994) or his son Ekbert II. Foundation for Medieval Genealogy, however, cites a source in which she is referred to as the sister of Pope Leo IX
