There are no sources about him until 1207 when he participated in the expedition organized by Marco Sanudo for the conquest of the Greek islands which, three years after the fall of Constantinople to the Fourth Crusade, had not yet been occupied by the victors.
During the campaign of 1207, the island of Andros had been assigned to Marino Dandolo but at an unknown date (probably between 1238 and 1239), Geremia had seized it by force.
Andrea and Geremia were also ordered to present themselves before the Doge and submit to the Council's decision by 29 June 1244, on pain of exile from Venice and the auctioning of their possessions for the benefit of the dispossessed Dandolo family.
From the terms of the agreement, it is clear that he was no longer in direct possession of Andros, which may have devolved to a vassal of the Duchy of Naxos.
After fulfilling his obligations, on 28 March 1253, his exile was lifted by the Great Council, but the reclamation of his auctioned goods was long-drawn out affair; even in 1280, years after his death, some still had not been recovered.
