Then occurred an event, which made a lasting impression upon the history of Cumberland, for the Chronicon Cumbrie relates how the said William Meschin sub-granted a thin strip of Copeland, abutting northward on the river Derwent, to his neighbour Waldeve son of Gospatric, to be held of himself, the grantor, as superior lord. Waldeve was, of course, the over Lord of the district known as Allerdale below Derwent.
That thin strip crystallized as the Honour of Cocker¬mouth. From the ecclesiastical point of view the same thin strip, containing the five vills of 1. Brigham, 2. Eagles¬field, 3. Dean cum Branthwaite, 4. Greysouthen and 5. the two Cliftons cum Stainburn, and lay, like its parent barony of Copeland, within the diocese of York [*].
William Meschin tenant ‘in capite’ fixed his residence at Egremont and consequently preferred to describe his own fee of Copeland as the ‘Barony of Egremont’ and built his castle at Egremont on the banks of the river Ehen.
