 After the Norman Conquest, William the Conqueror undertook a wholesale redistribution of land from the English to the Norman nobles.His "Great Survey", the "Domesday Book" completed at the end of 1086, records Arlingham as "Erlingeham" (meaning 'Homestead of the Eorlingas', the tribe of Eorla) as being "King's land and part of the Manor of Berkely, containing 1400 acres", making Arlingham an exclave of the Hundred of Berkeley.In the 12th century the Abbott of St. Augustine's Abbey Bristol (the Abbey later became Bristol Cathedral after the Dissolution of the Monasteries), had Manor and lands in Arlingham, which included fishing rights in the River Severn.
