King Roger of Sicily was a very great king. He won and subdued all Apulia, and many large islands besides in the Greek sea; and therefore he was called Roger the Great. His son was William, king of Sicily, who for a long time had great hostility with the emperor of Constantinople. King William had three daughters, but no son. One of his daughters he married to the Emperor Henry, a son of the Emperor Frederik; and their son was Frederik, who for a short time after was emperor of Rome. His second daughter was married to the Duke of Kipr. The third daughter, Margaret, was married to the chief of the corsairs; but the Emperor Henry killed both these brothers-in-law. The daughter of Roger the Great, king of Sicily, was married to the Emperor Manuel of Constantinople; and their son was the Emperor Kirjalax.
