GERBERGA (Nordhausen [913/14]-Reims 5 May 984, bur Abbaye de Reims). Liutprand states that the wife of "Gislebertum Lotharingorum ducem" was "regis sororem"[164]. Flodoard names her "Gerbergam" when recording her second marriage[165]. Her first husband had been a rival of King Heinrich I and maybe planned to establish himself as independent ruler in Lotharingia in 920[166]. As the marriage coincided with Giselbert being created dux, it was presumably arranged to confirm Giselbert's submission to King Heinrich. King Louis married Gerberga without the permission of her brother Otto I King of Germany, probably to increase his hold on Lotharingia (ruled by her first husband). Gerberga was active in the defence of Laon in 941 and of Reims in 946, accompanied her husband on expeditions to Aquitaine in 944 and Burgundy in 949, and was active during his period of imprisonment in 945/46[167]. An educated person, she commissioned from Adso of Moutier-en-Der the De ortu et tempore antichristi[168]. Her second husband gave her the abbey of Notre-Dame de Laon in 951, taken from his mother on her second marriage. Abbess of Notre Dame de Soissons in 959[169]. m firstly ([928/29]) GISELBERT Graf [von Maasgau], son of REGINAR [I] "Langhals" Graaf [van Maasgau] Comte de Hainaut & his wife Alberada --- (-drowned in the River Rhine Oct 929).
