Remarks:
4th Earl of Chester; also lord of Cumberland and viscount of Bayeux [the Bessin] in Normandy. He became earl of Chester in 1120 following the death of his first cousin, Richard d'Avranches, 3rd earl of Chester, who died without heirs in the sinking of the White Ship on November 25, 1120. He appears to have surrendered the lordship of Cumberland, which he had obtained shortly before from Henry I, on his accession as earl of Chester. In 1124 he was commander of the royal forces in Normandy. The sobriquet, Òle MeschinÓ means Òthe Young,Ó from the Latin Òmischinus,Ó French ÒmeschinÓ [le jeune]. He is also called Briquessart from Briquessart in the commune of Livry, where the earthworks of his castle are still visible.
