Guy de Lusignan (c. 1275–1303), Constable of Cyprus, was the son of Hugh III of Cyprus and Isabella of Ibelin. He never reigned — he died in 1303, twenty-one years before his uncle Henry II's death — but he is admitted here as the non-royal succession carrier through whom his son Hugh IV inherited the throne of Cyprus and the titular crown of Jerusalem. His admission makes the Hugh III → Hugh IV succession canonical rather than prose-only.
