 However some time during the reign of William Rufus, Poitou gave Blackburnshire and the Bowland area, north of the River Ribble (under Craven in the Domesday Book) to the Baron of Pontefract, Robert de Lacy.When de Poitou lost his English holdings in 1102, Henry I not only allowed de Lacy to keep these lands, but added to them with the vills of Chipping, Aighton and Dutton.Clitheroe became the centre of this new honour.
