DEDDINGTON, a parish (formerly a market-town) in the hundred of WOOTTON, county of OXFORD, containing, with the townships of Clifton and Hempton, 1847 inhabitants, of which number, 1404 are in the town of Peddington, 16 miles (N. byW.) from Oxford, and 69 (N.W.) from London. This place, though formerly of some importance, having sent members to two parliaments in the reign of Edward I., is now an inconsiderable town. According to Dr. Plot, a castle was anciently built here, either by the Saxons or the Danes, but no vestiges of it can be traced, nor is there any thing of importance occurring in the history of the place, except its having been the retreat of Piers Gavestone, the favourite of Edward II., a short time previous to his capture by the Earl of Warwick, and his decapitation on Blacklow Hill, and subsequently the possession of his successor in that monarch's aifections, Hugh de Spencer, who suffered a similar fate. The town, which has been noted for its malt liquor, contains several well-built houses, and is well supplied with water: a branch of the Oxford and London canal passes through the parish. The market has been discontinued; but a fair for cattle is still held on the 22nd of November. A bailiff is annually appointed at the court leet of the lord of the manor. The living is a discharged vicarage, in the archdeaconry and diocese of Oxford, rated in the king's books at £15. 9. 4., endowed with £600 private benefaction, £200 royal bounty, and £1400 parliamentary grant, and in the patronage of the Dean and Canons of Windsor. The church is dedicated to St. Peter and St. Paul. Parochial schools for boys and girlg are supported by subscription. Almshouses for four aged men and four aged women, were founded in 1818, and are endowed with property arising from various benefactions vested in feoffees for the benefit of the poor, producing about £140 per annum. In the neighbourhood are two mineral springs, now neglected, one of which is said to have been highly impregnated -with sulphur. Lord Chief Justice Scroggs, who nourished in the reign of Charles II., was a native of this parish; and Sir Thomas Pope, an eminent statesman, and founder of Trinity College, Oxford, is said to have been born here, in 1507.
