Baron Boston, of Boston in the County of Lincoln, is a title in the Peerage of Great Britain. It was created in 1761 for the court official and former Member of Parliament, Sir William Irby, 2nd Baronet. He had earlier represented Launceston and Bodmin in the House of Commons. He was the son of Edward Irby, Member of Parliament for Boston, who was created a baronet, of Whaplode and Boston in the County of Lincoln, in the Baronetage of England on 13 April 1704. Lord Boston's son, the second Baron, was a Lord of the Bedchamber to both George III and George IV. The title followed the line of his eldest son, the third Baron, until the death of the latter's great-great-grandson, the eighth Baron, in 1972. The late Baron was succeeded by his third cousin once removed, the ninth Baron. He was the great-grandson of Rear-Admiral Frederick Paul Irby, second son of the second Baron. Since 2007, the title is held by his grandson, the 11th Baron.[1]
The family seat was Hedsor House, Hedsor, Buckinghamshire. The family also owned Plas Llanidan[2] and land at Lligwy in Moelfre, Anglesey, Wales.[3]
The heir apparent is the present holder's son, the Hon. Thomas William George Boteler Irby (born 1998).
