[5] La Vita Johannis Gorziensis, written in 980, indicates that he was of royal descent through both his paternal and maternal lines, though the text spells out that the connection went back "several" generations.

In 929 Adalbero was elected by the clergy and the people to succeed Benneon of Metz [fr] whose own episcopal term had recently ended badly.

[2] As Bishop of Metz, Adalbero's enthusiastic promotion of a revival in monasticism gained him the soubriquet "father of the monks".

Starting in 933/934 he became a driving force behind the revival of Gorze Abbey, appointing the energetic Abbot John to lead the project on site.

[6] It is recorded that Adalbero later returned to Archbishop Bruno of Cologne, the piece of St Peter's ferula (staff), a treasured relic which had been sent across to Metz at the time of the Hunnish invasions.

On the other hand, Duke Conrad was killed in battle in 955, and there are no indications of any successor bishop having been appointed at Metz till after Adalbero's death.
