In 1148, John returned to Hilaire, Bishop of Chichester, lands belonging to his diocese which his father had usurped during the troubled reign of Stephen. John had to take refuge in the summer of 1167 in Drincourt during the invasion of his estates by the troops of Louis VII, an ally of Thierry, Count of Flanders.
John married Alice, daughter of William d'Aubigny, 1st Earl of Arundel and Adeliza of Louvain, the widow of King Henry I of England. John and Alice had three children:
- Henry II of Eu, 6th Count of Eu, Lord of Hastings
- Robert of Eu
- Mathilde d'Eu, married to Henry d'Estouteville, Seigneur of Valmont.
- John d'Eu, Lord of Eu and Hastings, issued a confirmation charter to Robertsbridge Abbey, Sussex, c. 1198–1205.
John was succeeded as Count of Eu and Lord of Hastings by his son Henry upon his death. John was buried at Fécamp Abbey, where many of his sons and grandsons would also be interred.
