He was born in Normandy on the same day that his father"s rival, Eustace IV of Boulogne, died.
He died in April 1156, aged two. This was due to a seizure at Wallingford Castle, and he was buried in Reading Abbey at the feet of his great-grandfather Henry I.
At the time of his death, he was reigning as Count of Poitiers, as his mother had ceded the county to him. Some authorities say he also held the title of "Archbishop of York", but this is probably an error.
His half-brother Geoffrey (died 1212), who was born a year before William, did later hold that office, causing the confusion.
