Halton (barony) The Barony of Halton, in Cheshire, England, comprised a succession of 15 barons who held under the overlordship of the County Palatine of Chester ruled by the Earl of Chester. It was not therefore an English feudal barony which was under full royal jurisdiction, which is the usual sense of the term, but a separate class of barony within a palatinate. After the Norman conquest, William the Conqueror created three earldoms to protect his border with Wales, namely Shrewsbury, Hereford and Chester. Hugh Lupus was appointed Earl of Chester and he appointed his cousin, Nigel of Cotentin, as the first Baron of Halton. Halton was a village in Cheshire which is now part of the town of Runcorn. At its centre is a rocky prominence on which was built Halton Castle, the seat of the Barons of Halton; the castle is now a ruin.
