谁嫁给了James I of Cyprus？

James I (French: Jacques de Lusignan; 1334 – September 9, 1398) was the youngest son of King Hugh IV of Cyprus and by 1369 held the title "Constable of Jerusalem." When his nephew Peter II died in 1382, he became King of Cyprus. James was also crowned King of Jerusalem in 1389 and assumed the title of King of Armenia in 1393, which was formally given to him in 1396.

James was the third son of Hugh IV of Cyprus and his second wife, Alix of Ibelin. His older half-brother was Guy, Prince of Galilee (1320–43), and his two brothers were Peter I, King of Cyprus (1328–1369), and John of Lusignan, Prince of Antioch (1329–1375). Before becoming king, James had other offices and was known for his resistance against the Genoese invasion of Cyprus.

Helvis of Brunswick-Grubenhagen (1353 – 15 January 1421) was the queen consort of Cyprus and titular queen consort of Armenia as the wife of King James I of Cyprus. She was styled Queen of Cyprus from 1382 to 1398; although at the time of his ascension to the Cypriot throne, she and James were imprisoned in Genoa after they had been captured by the Genoese on the island of Rhodes. Almost all of Helvis 11 children were born to her while she was held prisoner. In 1385, after negotiations and many ruinous concessions to the Genoese, they were released and James was crowned king. In 1393, she became Queen of Armenia.
