Hugh died in 1196.
In 1197 she accompanied an army to besiege Jebail, which had been captured by the Muslims, and bribed a guard to open up the city to them.
She seems to have died soon after this.

Raymond IV, Count of Tripoli

He was the son of Bohemond III of Antioch and Orgueilleuse d' Harenc.
When Raymond III of Tripoli died in 1187 without heirs, he left his county to Raymond, who was his godson.
After two years, Bohemond III desired to keep his heir closer to his Antiochene court and so brought him back and sent his second son, Bohemond IV, as count to Tripoli.
After the elder Bohemond was captured by Leo II of Armenia, Raymond acted as regent until his return.
In 1195, Raymond married Alice of Armenia, Leo II's niece, the daughter of Roupen III, to solidify the peace.
They had one son, Raymond- Roupen, who fought for his inheritance as the eldest grandson of Bohemond III.

Henry of Antioch
Henry of Antioch( b. 1198–1217, d. 18/27 of June, 1276), alternately known as Henri de Poitiers or Henry of Poitiers, was the son of Bohemond IV of Antioch, Prince of Antioch and his first wife Plaisance Embriaco de Giblet.
In 1233 Henry married Isabella de Lusignan, the daughter of Hugh I of Cyprus and Alice of Champagne.
In 1263, she was appointed regent of Jerusalem and in turn appointed Henry bailli of the kingdom.
Henry and Isabella had two children:
His children both adopted their mother's surname of" de Lusignan", founding the Second House of Lusignan.
Henry drowned at sea of Tyre in June, 1276 while sailing to Tripoli in a German ship.
His body was recovered and, after the death of Hugh III, both were returned to Nicosia for burial.
Bohemond IV of Antioch
Bohemond IV of Antioch, also known as Bohemond the One-Eyed (1175–1233), was Count of Tripoli from 1187 to 1233, and Prince of Antioch from 1201 to 1216 and from 1219 to 1233.
He was the younger son of Bohemond III of Antioch.
The dying Raymond III of Tripoli offered his county to Bohemond's elder brother, Raymond, but their father sent Bohemond to Tripoli in late 1187.
Saladin, the Ayyubid sultan of Egypt and Syria, conquered the county, save for the capital and two fortresses, in summer 1188.
Raymond died in early 1197, leaving a posthumous son, Raymond-Roupen.
Raymond-Roupen's mother, Alice, was the niece of Leo I of Cilicia who persuaded the Antiochene noblemen to acknowledge Raymond-Roupen's right to succeed his grandfather.
However, the Latin and Greek burghers proclaimed Bohemond heir to his father.
After his father died in April 1201, Bohemond seized Antioch with the support of the burghers, the Knights Templar and Hospitallers, and the Italian merchants.
Bohemond made an alliance with Az-Zahir Ghazi, the Ayyubid emir of Aleppo, and Kaykaus I, the Seljuq sultan of Rum, who often invaded Cilicia during the following years, to prevent Leo I from attacking Antioch.
Conflicts between Bohemond and the Latin Patriarchs of Antioch enabled Raymond-Roupen to seize Antioch in 1216, but Bohemond regained the principality in 1219.
After Leo I's death, Bohemond tried to secure Cilicia to his younger son, Philip, but Constantine of Baberon, who had administered Cilicia during the previous years, imprisoned Philip in 1224.
Bohemond allied with Kayqubad I, sultan of Rum, but he could not prevent Philip's murder in 1225.
Isabella, Queen of Armenia
Isabella , also Isabel (27 January 1216/ 25 January 1217 – 23 January 1252) was queen regnant of Armenian Cilicia from 1219 until her death.
She was proclaimed queen under the regency of Adam of Baghras.
But he was assassinated; and Constantine of Baberon (of the Hethumian family) was nominated as guardian.
At this juncture, Raymond-Roupen, grandson of Roupen III (the elder brother of Isabella’s father, King Leo I) set up a claim to the throne of Cilicia; but he was defeated, captured, and executed.
Constantine of Barbaron was soon convinced to seek an alliance with Prince Bohemond IV of Antioch, and he arranged a marriage between the young princess and Philip, a son of Bohemond IV.
Philip, however, offended the Armenians’ sensibilities, and even despoiled the royal palace, sending the royal crown to Antioch; therefore, he was confined in a prison in Sis (now "Kozan" in Turkey), where he died, presumably poisoned.
The unhappy young Isabella was forced to marry Constantine of Barbaron’s son, Hethum; although for many years she refused to live with him, but in the end she relented.
The apparent unification in marriage of the two principal dynastic forces of Cilicia ("i.e.", the Roupenids and the Hethumids) ended a century of dynastic and territorial rivalry and brought the Hethumids to the forefront of political dominance in Cilician Armenia.
Bohemond III of Antioch
Bohemond III of Antioch, also known as Bohemond the Child or the Stammerer (1148–1201), was Prince of Antioch from 1163 to 1201.
He was the elder son of Constance of Antioch and her first husband, Raymond of Poitiers.
Bohemond ascended to the throne after the Antiochene noblemen dethroned his mother with the assistance of Thoros II, Lord of Armenian Cilicia.
He fell into captivity in the Battle of Artah in 1164, but the victorious Nur ad-Din, atabeg of Aleppo released him to avoid coming into conflict with the Byzantine Empire.
Bohemond went to Constantinople to pay homage to Manuel I Komnenos, who persuaded him to install a Greek Orthodox Patriarch in Antioch.
The Latin Patriarch of Antioch, Aimery of Limoges, placed Antioch under interdict.
Bohemond restored Aimery only after the Greek patriarch died during an earthquake in 1170.
Bohemond remained a close ally of the Byzantine Empire.
He fought against Mleh, Lord of Armenian Cilicia, assisting in the restoration of Byzantine rule in the Cilician plain.
He also made alliances with the Muslim rulers of Aleppo and Damascus against Saladin, who had begun to unite the Muslim countries along the borders of the crusader states.
Since Bohemond repudiated his second wife and married an Antiochene lady, Patriarch Aimery excommunicated him in 1180.
Bohemond forced the Armenian rulers of Cilicia to accept his suzerainty in the late 1180s.
He also secured the County of Tripoli for his second son, Bohemond, in 1187.
However, Saladin occupied almost the whole Principality of Antioch in the summer of 1188.
To preserve the peace with Saladin, Bohemond did not provide military assistance to the crusaders during the Third Crusade.
Leo of Cilicia's expansionist policy in the 1190s gave rise to a lasting conflict between Antioch and Cilicia.
Bohemond was captured in 1194 by Leo, who tried to seize Antioch, but the burghers formed a commune and expelled the Armenian soldiers from the town.
Bohemond was released only after he acknowledged Leo's independence.
New conflicts emerged after Bohemond's eldest son, Raymond, died in 1197.
Raymond's widow, who was Leo's niece, gave birth to a posthumous son, Raymond-Roupen, but Bohemond's younger son, Bohemond of Tripoli, wanted to secure his succession in Antioch with the assistance of the commune.
The elderly Bohemond seems to have supported his son during his last years.
The War of the Antiochene Succession began with Bohemond's death and lasted until 1219.
