"A Vision of Britain through Time" has a map of the hundreds of Surrey dated 1832.
As can be seen from the list below Wallington Hundred covered much of the area of the modern London Borough of Croydon. It also stretches into the London Borough of Sutton and the London Borough of Merton to the north and northwest. Two parishes are still in Surrey, the county outside this part of Greater London.
