Royal bastard in the context of Order of Aviz

Elizabeth I (7 September 1533 – 24 March 1603) was the Queen of England and Ireland from 17 November 1558 until her death. She was the last and longest reigning monarch of the House of Tudor. Her eventful reign, and its effect on history and culture, gave name to the Elizabethan era.

Elizabeth was the only surviving child of Henry VIII and his second wife, Anne Boleyn. When Elizabeth was two years old, her parents' marriage was annulled, her mother was executed, and Elizabeth was declared illegitimate. Henry restored her to the line of succession when she was 10. After Henry's death in 1547, Elizabeth's younger half-brother Edward VI ruled until his own death in 1553, bequeathing the crown to a Protestant cousin, Lady Jane Grey, and ignoring the claims of his two half-sisters, Mary and Elizabeth, despite statutes to the contrary. Edward's will was quickly set aside and the Catholic Mary became queen, deposing Jane. During Mary's reign, Elizabeth was imprisoned for nearly a year on suspicion of supporting Protestant rebels.

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.
