Warrington is a name that first reached England following the Norman Conquest of 1066. The Warrington family lived in Lancashire, at Warrington, a borough, markettown, and parish, and the head of a union, in the hundred of West Derby. It was originally a British town, and on the invasion of the Romans under Agricola in the year 79, converted into a Roman station. The Saxons named the place Weringtun, from the Saxon Wæring, a fortification, and tun, a town. It later formed part of the demesne of Edward the Confessor and became head of a deanery, of which the jurisdiction still remains. In Domesday Book it is listed under the name of Wallintun; and in the reign of Edward I was in the possession of William le Boteler, who obtained for it the grant of a market, and other privileges.
