谁嫁给了Helena Angelina Komnene？

Helena Angelina Komnene (Greek: Ἑλένη Ἀγγελίνα Κομνηνή, fl. 1275–91) was a daughter of the Greek sebastokrator John I Doukas, ruler of Thessaly in ca. 1268–1289, and a Greek princess of Aromanian origin, known only by her monastic name, Hypomone.

In 1275, the Byzantine Emperor Michael VIII Palaiologos sent a large army to subdue her recalcitrant father. The Byzantine army besieged John's capital of Neopatras, but he managed to flee and seek the aid of the Duke of Athens, John I de la Roche (r. 1263–1280). John I gave the necessary aid to the sebastokrator, in exchange for the marriage of Helena to his brother, William I de la Roche, the future Duke of Athens (r. 1280–1287). The Duchy also acquired the towns of Siderokastron, Zeitounion, Gravia, and Gardiki as her dowry.

The couple had a son, Guy II de la Roche (r. 1287–1308). Following William's death, Helena served as regent for her underage son until his coming of age. In 1289, she refused to recognize the suzerainty of the new Prince of Achaea, Florent of Hainaut, and the Angevin King of Naples, Charles II, as the common liege-lord of all Frankish states in Greece, had to force her to submit. In 1291 she married Hugh of Brienne, Count of Lecce, who became the bailli of the Athenian duchy. This allowed Helena once again to challenge Achaen suzerainty, and insist on her right to do homage directly to the King of Naples. Charles II vacillated, but in the end Florent of Hainaut prevailed, and when Guy II of Athens came of age in 1296, he recognized Florent and his wife, Isabella of Villehardouin, as his liege-lords.

William I de la Roche (died 1287) succeeded his brother, John I, as Duke of Athens in 1280. He was the son of Guy I de la Roche.

William reversed the territorial losses of his brother's reign, extending his control over Lamia and Gardiki. He married Helena Angelina Komnene, daughter of John I Doukas, ruler of Thessaly, securing a military alliance with him.

In 1285, while Charles II of Naples, the nominal prince of Achaea, was imprisoned, Robert of Artois, the regent of the kingdom, named William bailiff and vicar-general of Achaea. William built the castle of Dimatra to defend Messenia from the Byzantine Empire. He was then the most powerful baron in Frankish Greece. In 1286, he arbitrated the succession of the March of Bodonitsa following the death of Isabella Pallavicini. He chose her cousin Thomas over her widower Antoine le Flamenc.

William's rule was peaceful but short, as he died two years after assuming power in Achaea (1287). He was succeeded by his son Guy, who was seven years old.

Hugh, Count of Brienne and Lecce (c. 1240 – 9 August 1296) was the second surviving son of Count Walter IV of Brienne and Marie de Lusignan of Cyprus.
