Marino I dalle Carceri

Marino I dalle Carceri (died 1247) was a Lombard hexarch of Negroponte who ruled the northern triarchy from Oreos. Son of Redondello dalle Carceri and nephew of Ravano, he married Margherita, daughter of Pecoraro da Mercanuovo.

When Ravano died, the Venetian bailo split the island into six hexarchies; Marino took a northern share with his brother Rizzardo. He ruled until 1247, and his son Narzotto later became triarch of Chalkis.
