Lancashire Domesday Book tenants-in-chief

The Domesday Book of 1086 AD identifies King William the Conqueror's tenants-in-chief for historic Lancashire within Cestrescire (Cheshire) and Eurvicscire (Yorkshire). At the time of the Norman Conquest of England, the County of Cheshire included Inter Ripam et Mersam (between the River Ribble and River Mersey) which became South Lancashire (now including parts of Merseyside and Greater Manchester), while the West Riding (West Treding) of the County of Yorkshire included what became North Lancashire. Tenants-in-chief for lands in historic Cheshire:


 * Roger de Poitou was awarded over 50 lands including Blackburn, Crosby, Formby, Huyton, Kirkby, Knowsley, Leyland, Maghull, Manchester, Newton-le-Willows, Rochdale, Salford, Skelmersdale, Speke, Upholland, Warrington and West Derby. He was the son of Roger de Montgomery and he was one of William the Conqueror's main advisers. King Henry I confiscated all of his land between the River Ribble and the River Mersey, after Roger and his brothers' failed rebellion in 1102.
