  Research Notes:

Jackman suggests that the mother of Hunfried canon at Strasbourg was the daughter of Adalberto associate King of Italy. He bases this on onomastic reasons, in particular the importation of the Ivrean name Berengar 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 Unruoch was related to the Unruochingi Counts of Friulia. ¹
