 At the time of Edward the Confessor , the parishes of Ruislip and Ickenham belonged to a Saxon named Wlward Wit , a thane of the king who owned land in 11 counties . Ruislip parish included what is now the modern Ruislip , Northwood , Eastcote , Ruislip Manor and South Ruislip . Wit lost much of his land during the Norman conquest of England ; Arnulf de Hesdin took control of Ruislip – his ownership is recorded within the 1086 Domesday Book .
