Оттон I Великий
When Berengar was fighting against Otto I, Holy Roman Emperor in the early 960s, Willa and her sons, Adalbert of Italy and Guy of Ivrea were frequently by his side. After Otto deposed Berengar, Willa and Berengar were taken as prisoners to Bavaria. After Berengar's death in 966 Willa retired to a nunnery in Bamberg, where she remained for the rest of her life. The date of her death is not known exactly.
