Duke of St Albans is a title in the Peerage of England. It was created in 1684 for Charles Beauclerk, 1st Earl of Burford, then 14 years old. King Charles II had accepted that Burford was his illegitimate son by Nell Gwyn, an actress, and awarded him the dukedom just as he had conferred those of Monmouth, Southampton, Grafton, Northumberland, and Richmond and Lennox on his other illegitimate sons who married.
The subsidiary titles of the Duke are Earl of Burford, in the County of Oxford (1676), Baron Heddington, in the same (1676) and Baron Vere, of Hanworth in the County of Middlesex (1750). The Earldom and the Barony of Heddington are in the Peerage of England, and the Barony of Vere is in the Peerage of Great Britain. The dukes hold the hereditary title of Grand Falconer of England, and until the end of the 18th century they were Hereditary Registrars of the Court of Chancery.
