  Research Notes:

The Annales Lobienses name "Tietberga, sorore Hucberti abbatis" as lawful wife of "Lotharius". The Annales Bertiniani name "Teutbergam" as "materteram suam [=Bosone filio Buvini comitis]". The Chronicle of Alberic de Trois-Fontaines names "Thieberga regina legitima uxore [Lotharii]", specifying that she relied on the advice of "Bosonis comitis" at the time of her repudiation, although her relationship to him is not specified. Herimannus names "Tiohtpirga uxore legitima" of King Lothaire II when recording that he repudiated her. She protected the wife of Boso Count in Italy after she deserted her husband. She was repudiated on the grounds of her alleged incest with her brother Hubert. Her husband kept her prisoner after separating from her. The Annales Bertiniani record that "uxor Lotharii" fled to "fratrem suum Hucbertum in regno Karli" in 860. She escaped in 860 and sought refuge with Charles II "le Chauve" King of the West Franks, who gave her the abbey of Avenay in the diocese of Reims. The Annales Bertiniani records that "uxore [Lothario]" gave support to "uxori Bosonis et Balduino qui filiam eius [=Karoli regis] furatus fuerat in uxorem".

Abbess of Sainte Glossinde at Metz 869. "Heccardus comes" names "…Teutbergane uxore Lotharii…" among the beneficiaries under his testamentary disposition dated to [Jan 876]. It is not certain that this refers to the separated wife of King Lothaire II, but no other "Teutberga/Lothaire" couple has been identified at the time. If this identification is correct, it suggests a family relationship between Teutberga and Ekkehard, which has not yet been identified. ¹
