He was a son of Gregory I and Maria, brother of Popes Benedict VIII and John XIX, and brother-in-law of Thrasimund III of Spoleto.
He also bore the titular comes sacri palatii Lateranensis ("Count of the Sacred Lateran Palace"), which signified his ecclesiastical function in the papal curia.
During the pontificate of his brother John XIX, he was made a senator, but he had to abandon this title for the aforemention consular dignity in order to avoid tensions with the Emperor Henry II.
Alberic does not appear in sources after 1033, when he left the comital powers to his son the newly elected pope.
He married Ermelina and his son Theophylact III (or IV) became Pope Benedict IX in 1032.
