In 1870-72, John Marius Wilson's Imperial Gazetteer of England and Wales described Grendon Underwood like this:
GRENDON UNDERWOOD, a village and a parish in Aylesbury district, Bucks. The village stands 4 miles SW of Claydon r. station, and 6½ ESE of Bicester; is characterized, in an old Buckinghamshire rhyme, as " the dirtiest town that ever stood, " but is now cleaner; and is said to have furnished to Shakespeare, on occasion of his spending a night in it, some of the humour of his " Midsummer Night's Dream. " The parish comprises 3, 670 acres; and its post town is Middle Claydon under Winslow. ...
Real property, £2, 219. Pop., 451. Houses, 97. The property is divided among a few. The manor belonged anciently to Almeric de St. Amand, a godfather of Edward I.; passed to the Pigotts; and belongs now to J. Jervoes, Esq. The living is a rectory in the diocese of Oxford. Value, £360. * Patron, W. Pigott, EsqThe church is ancient but good; and contains monuments of the Pigotts, and one of Lord Saye and Sele. There are a Baptist chapel, and an endowed school.
