Mary of Lusignan

Mary of Lusignan (1215–1251) was the eldest daughter of King Hugh I of Cyprus and Alice of Champagne, and a granddaughter of Queen Isabella I of Jerusalem. A betrothal to Peter I of Brittany was called off in 1229, and in 1233 she married Count Walter IV of Brienne.

Her husband was captured at La Forbie and murdered in Cairo in October 1244, leaving their sons John and Hugh. Mary retired to the Cypriot court and died there in 1251.
