The prolific 19th-century French writer Baron Ernouf suggested that Waldrada was of noble Gallo-Roman descent,[1] sister of Thietgaud, the bishop of Trier, and niece of Gunther, archbishop of Cologne.
[3] The Vita Sancti Deicoli states that Waldrada was related to Eberhard II, Count of Nordgau (included Strasbourg) and the family of Etichonids, though this is a late 10th-century source and so may not be entirely reliable on this question.
However, Hucbert took up arms on his sister's behalf, and after she had submitted successfully to the ordeal of water, Lothair was compelled to restore her in 858.
Still pursuing his purpose, he won the support of his brother, Emperor Louis II, by a cession of lands and obtained the consent of the local clergy to the annulment and to his marriage with Waldrada, which took place in 862.
Thus, Lothair began to seek the permission of the newly appointed Pope Adrian II to again put Teutberga aside and marry Waldrada, riding to Rome to speak with him on the matter in 869.
