Of one thing you may be certain: Neither Walderne nor his brother, Hamon, were at Hastings. They had been killed at the Battle of Vale-es-Dunes (1047) when they were contesting the right of William 'the Bastard' to become the next Duke of Normandy. Their other brother, Hubert, actually fought on the side of William 'the Bastard' at Val-es-Dunes and, as a result of this, his family received huge grants of land after the Conquest and became the King's 'dapifer' as you will gather from the St Clairs of the Isles.

Huber era de otra madre, que quizas por celos le hizo pelear con William the Bastard/Conqueror ya que no podia aspirar a mas dentro del clan, que aparentemente estaba opuesto a William desde que quisieron derrocarlo en 1047.
