His parentage is confirmed by the charter dated 24 Jun 1147 under which his grandson “Gonnarius...Turritanorum rex et dominus” donated property to Monte Cassino before leaving for Jerusalem, in memory of “atavus meus Baraso rex, Marianus avus noster, Constantinus...genitor noster et Marchusa regina uxor eius...”. “Domino Barasone et nepote eius donno Marianus in renno quo dicitur Ore...donnicelo Mariane et donnicelo Petru et donnicelo Comita” donated property to the monastery of S. Benedetto di Monte Cassino by charter dated 1064. Pope Gregory VII wrote to “Mariano Turrensi, Orroco Arborensi, Orroco Caralitano et Constantino Gallurensi iudicibus Sardiniæ” dated 14 Oct 1073.
The name of Mariano´s wife is not known. Fara records “Susannam Gunale, seu de Zori” as the wife of “Marianus II in iudicatu Turritano”. This information has not been confirmed by primary source evidence. 1
