The parishes and major newer settlements in the Hundred. For some years until c.1880s reforms Northolt and Hanwell enjoyed small detached parts (exclaves). As to Northolt, in Greenford lay a small exclave and enclave of agricultural land, the smaller of which was 2.5 acres (expanded on map as too small to show), the larger, 47. Cowley completely consisted of enclaves in Hillingdon parish. Its parcels have therefore given way to a more workable modern definition, Cowley Peachey close to the site of its main manor.
