Geremia Ghisi was a Venetian nobleman who in c. 1207, following the Fourth Crusade, captured the Greek islands of Skiathos, Skopelos, and Skyros and became their lord, while his brother Andrea Ghisi conquered the islands of Tinos and Mykonos. Their sister or half-sister, Agnese Ghisi, married Othon de Cicon, who became the lord of Karystos on Euboea.
