The West Derby Hundred (also known as West Derbyshire) is one of the six subdivisions of the historic county of Lancashire, in northern England. Its name alludes to its judicial centre being the township of West Derby (the suffix -shire meaning the territory was appropriated to the prefixed settlement). It covered the southwest of Lancashire, containing the ancient ecclesiastical parishes of Walton, Sefton, Childwall, Huyton, Halsall, Altcar, North Meols, Ormskirk, Aughton, Warrington, Prescot, Wigan, Leigh, Liverpool, and Winwick. It corresponds roughly to areas of Merseyside north of the River Mersey and also covered parts of modern West Lancashire Borough, Wigan borough, Warrington Borough and Halton Borough. History Domesday Book When the Domesday Book was compiled, this hundred was composed of three separate hundreds of West Derby, Warrington and Newton-in-Makerfield. The hundreds possibly united in the reign of Henry I. The hundred is surrounded on the west by the Irish Sea and in the south west and south by the River Mersey and Glazebrook, to the east is Salford Hundred and to the north east the River Douglas and Leyland Hundred. Apart from the manor which contained West Derby Castle, said to have been built by Roger of Poitou, there were several other manors which were owned by the Lord of the manor for his own use. At the time of the Conquest these manors incorporated six berewicks encompassing the villages of Thingwall, Liverpool, Great Crosby, Aintree, Everton, Garston and Hale. The main landowner at the time is listed as Uhtred (sometimes spelt Uchtred or Uhtræd) Expansion of the boundaries By the end of the 12th century the three separate hundreds had united and West Derby Castle was an important administrative centre rivalling Lancaster in the north of the county. Its position was strengthened by its proximity to the Port of Liverpool, which was founded by King John, trade with Cheshire and the passage of ferries from Liverpool to Birkenhead. By 1327 West Derby Castle was reported to be in ruins. Court and laws on the hundred A Wapentake court was held every three weeks with the steward of the hundred officiating. There had been a courthouse in West Derby for over 1000 years since the time of the Vikings. The present courthouse situated in West Derby is from a building which was constructed during the reign of Queen Elizabeth I. The court was used for the presentation of minor offences,
