Helvis of Cyprus
Helvis of Lusignan (c. 1190 – c. 1218) was the daughter of Amalric II of Jerusalem, King of Cyprus, and his wife, Eschive d'Ibelin.
She was married twice.
Firstly, she was given in marriage to Eudes de Dampierre, a French knight, in about 1205.
With Eudes she had children, including eldest son
The details of her second marriage are revealed in a letter from Pope Innocent III to the archbishop of Antioch, dated September 1211.
Helvis had been taken from her husband (or fled him) by the young Raymond-Roupen of Antioch, designated heir to the Armenian throne, and although ecclesiastical authorities commanded the return to her husband Eudes de Dampierre, Helvis refused.
The young couple seem to have been encouraged by Helvis' brother-in-law, Walter of Montbéliard, which infuriated Helvis' brother King Hugh.
She and Raymond-Roupen had issue:

She was the elder daughter of Raymond-Roupen, prince of Antioch, and of Helvis of Lusignan.
She derived her title of Lady of Toron and claim to the throne of Armenia from her father.
Maria's paternal grandmother Alice became lady of Toron when emperor Frederick II, at the end of the Sixth Crusade, negotiated the return of lands conquered by Saladin; Maria succeeded her as she was the closest surviving relative.
In 1240 she married Philip of Montfort, Lord of Tyre, previously lord of Castres, and they had the following children:
She was the great-granddaughter of Roupen III, prince of Armenia (Roupen III's daughter was Alice), who had been succeeded by his brother Leo I. Maria thus unsuccessfully claimed rights to the throne of Armenia, something her father and grandmother had previously attempted and failed.
