Commentary
Charles Cawley: "Jackman speculates that Willibirg was the daughter of Adalbert II associate King of Italy & his wife Gerberge de Chalon, his reasoning being the onomastic connection between the Ivrean name 'Berengar', imported into the family of Liutold, and the use of 'Willa' among the ancestors of Adalbert King of Italy. However, another origin is suggested by the necrology of Zwiefalten which records the death "XIV Kal Dec" of "Unruoch proavus Liutoldi comitis". If this great grandfather were the father of Willibirg, it may also explain how the name Berenger entered the family, assuming that Unruoch was related to the Unruochingi Counts of Friulia."
