Her marriage is confirmed by the charter dated 994 under which "Artaldus comes, Gerardi quondam nobilis viri et Gimbergiæ filius" donated property to Savigny, subscribed by "Artaldi comitis et uxoris eius Theodebergiæ". "Artaldi comitis" donated property to the church of Saint-Irénée de Lyon by charter dated "pridie Kal Jul, xlviii anno regni Chunradi" ([985/86]), subscribed by "domni Artaldi…comitis…cum…conjuge…Tetbergiæ…domni Ugonis abbatis fratris eius, Adcelinæ abbatissæ…".
She married secondly ..., (repudiated) as his second wife, Pons Comte de Gévaudan et de Forez..., who was murdered by his stepson, Artaud Comte de Forez, in revenge for the repudiation of his mother Teutberga. "Poncius…comes…Gabalitanensis telluris necnon et Forensis patriæ" donated "ecclesiam Langat…in comitatu Gabalitensi, aliam ecclesiam…Favairolas…" to Saint-Julien de Brioude, for the souls of "genitorum suorum Stephani et Alais et uxoris eius Theotbergæ et filiorum eius Stephani et Poncii vel fratrum eius Bertrandi et Willelmus et nepotum eius Stephani, Rotberti et Willelmi", by charter dated Feb [1010], signed by "Roberti vicecomitis, Willelmi fratris eius…". "Tedberga comitissa" donated property to Cluny for the souls of "senioris mei Artaldi et filiorum meorum Artaldi et Giraldi" by charter dated Mar 1010. It is noted in the compilation that the document was subscribed by "Artaldi senioris eius, Artaldi filii eius, Giraldi filii eius" but that these subscriptions are only found in the cartulary version, the subscribers being unrecorded in the original charter. There is clearly a mismatch between these signatories and the date of death of Artaud [II], assuming that both his death date and the date of the charter are correct.
The 13th century obituary of the Eglise primatiale de Lyon records the death "V Id Jun" of "Tyeburga comitissa que dedit Sancto Stephano duos anaphos argenteos et unam fibulam auream cum preciosissimis gemmis". "Theuterga…comitissa" donated property to the abbey of Ainay for the soul of "senioris mei Artbaldi" by charter dated 13 Apr 1012, subscribed by "Rothildis filie sue". 1
