DATCHET, in the hundred and deanery of Burnham, lies on the banks of the Thames, two miles from Eton. The manor of Datchet was granted by King Edward III. in 1335 to William de Montacute, who the same year conveyed it to Sir John Molins. In 1558, the manor Datchet was leased by the crown to Sir Maurice Berkeley, who made it his residence. In 1631, the manor of Datchet, described as having formerly been parcel of the possessions of the castle and honour of Windsor; and the manor of Datchet-St. Helens, which had belonged to the priory of St. Helens, and had been afterwards annexed to the honour of Windsor, were granted by King Charles I. to Charles Harbord and others, by whom they were conveyed to Sir William Wheeler. In 1681, Andrew Pitcairne, alias Wheeler, conveyed this estate to Budd Wase, whose daughter and heir married John Whitfield esq. of Canterbury. It is now the property of the Duchess of Buccleugh, by inheritance from John Duke of Montagu, who in 1742 purchased it of two gentlemen, to whom it had been conveyed in 1730, by Mr. and Mrs. Whitfield.
In the parish church is the monument of Catharine, wife of Sir Maurice Berkeley, daughter of Lord Montjoy; that of Christopher Barker, printer to Queen Elizabeth, who died in 1607, and several of the family of Wheeler.
The rectory and advowson of the vicarage belonged anciently to the see of Lincoln: they were given by King Edward III. to the dean and chapter of Windsor. The bridge over the Thames at Datchet, originally built by Queen Anne, fell down in the year 1795, and has not since been rebuilt.
