Daughter of Richard, Graf von Metz, or of his brother, Gerhard.
Wipo names "Adalheida ex nobilissima gente Litharingorum oriunda…soror…comitem Gerhardi et Adalberti" and mother of "maioris Chuononis". Her second marriage is suggested by the Vita Meinwerci which names "Gebehardus iuvenis, frater imperatoris" when recording his tonsure at the synod in 1028, Gerhard not being named elsewhere as the full brother of Emperor Konrad I. 1
