Supporting claim
supported
Isabella of Cyprus (c. 1216–1264), daughter of Hugh I of Cyprus and Alix of Champagne, married Henry of Antioch. She is admitted here as the non-royal succession carrier through whom the Cyprus royal line reached her son Hugh III after Hugh II died childless in 1267. Her admission makes the succession canonical rather than prose-only.
