LANGLEY-MARISH, a parish in the hundred of STOKE, county of BUCKINGHAM, comprising a portion of the market-town of Colnbrook, and containing 1616 inhabitants. The living is a perpetual curacy, annexed to the vicarage of Wyrardisbury, in the archdeaconry of Buckingham, and diocese of Lincoln. The church, formerly a chapel of ease to the vicarage of Wyrardisbury, is dedicated to St. Mary, and was erected at the expense of the Kedermisters, of whom, Sir John Kedermister left for public use a small library, consisting of works chiefly on divinity; it is deposited in the church, the place being separated from the rest of the building by an ancient screen. He also founded, in 1649, almshouses for six poor persons; and Henry Seymour erected others for four inmates, in support of which, Captain Henry Seymour, in 1733, bequeathed £200 to purchase lands; the inmates receive about two shillings and sixpence each per week. There are two places of worship for dissenters, one of which belongs to the Independents. Courts leet and baron are annually held here.
