 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.
