↑ Biografia a Wikipedia IT di Oberto, in Wikipedia trovate 2016.
Oberto ebbe i seguenti figli: Ugo Alberto Azzo I, margravio di Milano Berta (?-1037), sposò prima Arduino d'Ivrea e quindi Olderico Manfredi II Adalberto Guido Obizzo, margravio della Liguria
↑ From Italian WP it seems clear that Berta was a daughter of Oberto. It is unclear whether she was a daughter from Railende or from his first marriage (but that seems to be the case for all his children)
