Isleworth Hundred


Isleworth Hundred was a subdivision of the historic county of Middlesex, England. In Domesday Book it was recorded as Hundeslaw Hundred.
It contained three parishes, whose acreage and square miles area is given as at the 1870s-1880s:
In 1801 Middlesex measured 734km². This, the smallest of the county's six hundreds, amounted to 5% of that area.
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 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 who took over the abbey's demense and built Syon House in the east of in Isleworth. The Domesday Book of 1086 names the unit 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.
