Nun at Chalon. The Annales Bertiniani record that "sororem Bernardi sanctimonialem" was drowned "in Ararim fluvium" in 834[400]. The Manual of Dhuoda names (in order) "Willelmus, Chungundis, Gariberga, Vuithbergis, Teddericus, Gothzelmus, Guarnarius, Rothlindis" as relatives of Bernard, husband of Doda[401]. The position of "Gariberga" in the list, immediately after "Chungundis" and before "Vuithbergis" (identifiable as the two wives of Guillaume), implies that she was the daughter of the former. Thegan's Vita Hludowici Imperatoris records that "sanctimonialis feminam…soror ducis Bernhardi…Gerbirch" was "iussit in vase vinatico claudere" and thrown into "flumen Ararim" [in 834][402]. The Vita Hludowici Imperatoris records that "Gotselmus comes itemque Sanila comes necnon et Madalelmus vassallus dominus" were beheaded at Chalon [in 834] and that "Gerberga filia quondam Willelmi comitis" was drowned[403].
