Edgware's origins can be traced back to the Anglo-Saxon period. The name "Edgware" is derived from "Ecgi's weir", implying a fishing or river-related settlement owned by an individual named Ecgi. Edgware, by the time of the Domesday book in 1086 was recorded as a small agricultural hamlet and its growth to the present day was influenced by its position on the route from London to the north of the country.
