General Notes

After Hugh III died in the Holy Land in 1104, the young boy Hugh IV was taken into King Henry I's court for his education, and is said to have been brought up as one of the King's sons. Hugh IV was knighted by Henry I but seems to have responded ungratefully, because he supported Amauri de Montfort in his rebellion against Henry in 1118, but he was forgiven by his royal patron and reinstated in his manors. In 1120 there were further intrigues, which induced the Pope to intervene and arrange a reconciliation. Hugh IV seems later to have atoned by founding (or confirming the foundaton of) the Abbey of Beaubec. In fact, in 1134 he was made, with William de Roumare, Earl of Lincoln, a Commander of the frontiers; but when Stephen became King, he once again showed inconsistancy in his loyalty.
In 1141 he was on the French side in a siege that the future King Henry II made of LaFerte, which was burnt down. At Whitsun 1147 he accompanied Louis the Young, King of France, on the Second Crusade.
After Henry II became King he siezed two of Hugh IV's manors - those of Wendover and Houghton, Bedfordshire, and he was much more unfortunate in 1173 when the young Prince Henry, in rebellion against his father Henry II, stormed and burnt Gournay Castle, taking Hugh and his elder son prisoner.
Like his father, Hugh IV was an enthusiastic supporter of the Crusades. At great age he took part in another expedition to Palestine in 1180 but died that same year in Italy.
Hugh IV married twice, each time into a leading family. Beatrice de Vermandois was a granddaughter of King Henri of France
