"Bonifacius marchio" appointed "filiis suos Maginfredum et Wilielmum adque Ugonem necnon Anselmum…et Anricum et Bonefacium minorem atque Odonem" as his heirs but disinherited "Bonifacium…incixie nominatum" by charter dated 1125. That he may have been born from the first marriage of his father is suggested by the charter dated 1196 under which his son "Bonifacius marchio de Cravexana" confirmed a donation to the monastery of San Stefano by "comitissa Adalasia avia mea". However, this charter could also refer to Bonifazio´s maternal grandmother, mother of Anselmo´s wife who is not otherwise known. "Marchiones filii domni Bonefatii…Manfredus, Wilielmus, Ugo, Anselmus, Enricus, Oddo Bouarius" donated property to the monastery of Staffarda by charter dated 9 Dec 1138. A charter dated 1140 records the agreement between the people of Genoa and "marchiones filios Bonefacii…Manfredum et Hugonem et Anselmum et Henricum et Ottonem", promising not to make war secretly with "Oberto comite Vintimillii" with the permission of Genoa.
Marchese di Ceva: a charter dated 22 Dec 1142 records the division of territories agreed between "Marchiones de Vasto…Mainfredum, Willielmum, Hugonem, Anselmum, Heinricum, Bonifacium et Oddonem filios quondam Bonifacii marchionis", under which Anselmo took "marchionatus Ceve".
The name of Anselmo's wife is not known. 1
