The hundred's name means 'enclosure of Gislhere'.{{Cite web|url=http://kepn.nottingham.ac.uk/map/place/Middlesex/Isleworth|title=Key to English Place-names}}

All of the above area in earliest records was exceptionally part of one manor, that of Isleworth based at Syon Abbey. The ownership separated in the middle of the medieval centuries; that of Heston was inherited from marriage of the daughter of Francis Child by the Earl of Jersey (with the Childs-Villier and later Villier surname) until the 20th century seated at the house built by Child employing Robert Adam, Osterley House in the north-east of Isleworth parish. The others two main manors fell into the hands of the Duke of Northumberland (with the surname Percy) who took over the abbey's demense and built Syon House in the east of in Isleworth.{{Cite web|url=http://www.british-history.ac.uk/vch/middx/vol3/pp83-84|title=The hundred of Isleworth | British History Online}} The Domesday Book of 1086 names the unit (in its heavily abbreviated fusion of Latin and French) Hounslow Hundred, a term never found again. Hampton to the south-west was stated to be under Hounslow Hundred Court at that date. In the many Feet of Fines, Assize Rolls, subsidy rolls and other central government and manorial court documents, save for a similar reference to Isleworth Hundred in a charter of the 12th century, Hampton is listed as unequivocally part of Spelthorne Hundred. This is explained by the abbey's and then the Percy family's holdings there.

Further named clusters of buildings (sometimes termed hamlets) emerged during its relevant currency:
