  Research Notes:

The Alberti Milioli Notarii Regini Liber de Temporibus records the arrival "in comitatu Lucensium" of "comes Sigifredus…cum tribus filiis…Sigifredus, Atto, Gerardus" and the building of "arcem Canosinam" by "comes Atto secundus frater" in May 915, although this date appears to be extremely early in light of the other known details of Atto's career. Adelaide Queen of Italy, widow of Lothar King of Italy, took refuge in the castle of Canossa after escaping from imprisonment by Berengario d´Ivrea who installed himself as King of Italy after the death of her husband in 950. "Atto filio quondam…Attoni de Comitatu Parmense" received money from "Adalberto qui et Atto, consobrino meo, filio quondam Aigefredi de Comitatu Lucensi" in 958. Adalberto Atto offered her hand in marriage to Emperor Otto I, who obliged King Berengario to raise his siege of Canossa.

He was referred to as Count in a [958/61] document, and as Conte di Reggio e Modena in 20 Apr 962. He was created Count of Mantua in 977.

The Alberti Milioli Notarii Regini Liber de Temporibus records the death "Id Feb" of "Atto" and his burial "in arce Canusina". 1
