Winslow was described in 1806 in "Magna Britannia" as follows:
WINSLOW, in the hundred of Cotslow and deanery of Muresley, is a market town about fifty miles from London, on the road to Buckingham. The market, which is on Thursdays, is very inconsiderable. It was granted, in 1235, to the abbott and convent of St. Albans, to whom the manor had been given by King Offa: the grant includes the right of holding a fair at the festival of St. Lawrence. There are now five annual fairs, March 20; Holy Thursday; August 21; September 22; and the Thursday before October 11. In 1599, the manor of Winslow was granted to Sir John Fortescue, who in 1619 sold it to Sir George Villiers, afterwards Duke of Buckingham: it was purchased in 1697, under an act of parliament, of the representatives of the second duke, by William Lowndes esq. secretary of the treasury, and is now the property of his great-grandson, William Selby esq. who took that name on succeeding to the estates bequeathed to him by the late ----- Selby esq. Mr. Selby has a seat at Winslow, which was built by Secretary Lowndes in the year 1700.
In the parish church, which is a spacious Gothic structure, contains no monuments worthy of notice. The great tithes, which were appropriated to the abbey of St. Albans, are the property of Mr. Selby: the vicarage, which is in the diocese of London, and in the peculiar jurisdiction of the archdeacon of St. Albans, is in the gift of the crown.
Mr. Joseph Rogers, in 1722, bequeathed a sum of money towards founding a charity school at this place.
The manor of Shipton, a hamlet of this parish, has passed with Winslow. Certain fields within the hamlet of Shipton, were inclosed by an act of parliament, passed in 1743; and the whole parish by an act passed in 1766, when allotments of land were assigned to the impropriator and vicar, and a small allotment for the poor.
