It would seem the arrangements for founding the Priory were well advanced by the time of the foundation charter, as opposed to the more gradual process at Wetheral and St Bees priories. Robert de Vaux gave the land of Lanercost "between the ancient wall and the Irthing and between Burth and Poltros, the vill of Walton by stated bounds, the church of that vill with the chapel of 'Treverman,' the churches of Irthington, Brampton, Carlaton and Farlam". The charter of foundation states that the benefaction was made for the sake of Henry II, and for the health of the souls of his father Hubert and his mother Grace.
