Although some modern histories have accorded Margaret the title "Princess of Wales", there is no contemporary record that Margaret used either that title, or her husband's earlier title of Prince of Powys; it is likely Margaret would have used neither. " Princess of Wales", an English honorific given to the wife of the English prince of Wales, was first used by Joan of Kent.  Only one wife of a Welsh prince is known to have used the title: Eleanor de Montfort, wife of Llywelyn ap Gruffudd, the last Prince of Wales. Duke of Cornwall is a title in the Peerage of England, traditionally held by the eldest son of the reigning British monarch, previously the English monarch.  The Duchy of Cornwall was the first duchy created in England and was established by royal charter in 1337.  The present duke is the Prince of Wales, the eldest son of Queen Elizabeth II.  His wife, Camilla, is the current Duchess. Edmund Sheffield, 1st Baron Sheffield, of Butterwick (22 November 1521 – 19 July 1549) was an English nobleman, the son of Sir Robert Sheffield (died 15 November 1531, son of Robert Sheffield and Helen Delves) and his second wife Jane Stanley, daughter of George Stanley, 9th Baron Strange and Joan le Strange, 9th Baroness Strange.  Through his mother, he was a second cousin once removed of the reigning English monarch, King Henry VIII. Margaret of England (20 July 1346 – October/December 1361) was a royal princess born in Windsor, the daughter of King Edward III of England and his consort, Philippa of Hainault.  Margaret would be the last princess born to a reigning English monarch for over a century, until the birth of Elizabeth of York in 1466.  She was also known as Margaret of Windsor. Cuckold's Point is the name given to part of a sharp bend on the River Thames on the Rotherhithe peninsula, south-east London, opposite the West India Docks.  It is to the north of Columbia Wharf.  The name came from a post surmounted by a pair of horns – indicating a cuckold: a man whose wife had cheated on him – that used to stand at the location, commemorating the starting point of the riotous Horn Fair – a procession which led to Charlton.  It is said that King John, or another English monarch, gave the fair as a concession, along with all the land from the point to Charlton, to a miller whose wife he had seduced after a hunting trip, though this story is disputed.

Elizabeth of York (11 February 1466 – 11 February 1503) was queen consort of England from 1486 until her death.  As the wife of Henry VII, she was the first Tudor queen.  She was the daughter of Edward IV and niece of Richard III, and she married the king following Henry's victory at the Battle of Bosworth which started the last phase of the Wars of the Roses.  She was the mother of King Henry VIII.  Therefore, she was the daughter, sister, niece, wife, mother, and grandmother of successive kings and queens of England. The chief governor was the senior official in the Dublin Castle administration, which maintained English and British rule in Ireland from the 1170s to 1922.  The chief governor was the viceroy of the English monarch (and later the British monarch) and presided over the Privy Council of Ireland.  In some periods he was in effective charge of the administration, subject only to the monarch in England; in others he was a figurehead and power was wielded by others. Maria Fortunata d'Este (24 November 1731 – 21 September 1803) was a Modenese princess by birth and a "princess of the blood of France" by marriage.
