Hvem daterede George IV of the United Kingdom?

Mary Robinson (née Darby; 27 November 1757 – 26 December 1800) was an English actress, poet, dramatist, novelist and celebrity figure. She lived in England, in the cities of Bristol and London; she also lived in France and Germany for a time. She enjoyed poetry from the age of seven and started working, first as a teacher and then as an actress, from the age of 14. She wrote many plays, poems and novels. She was a celebrity, gossiped about in newspapers, famous for her acting and writing. During her lifetime she was known as "the English Sappho". She earned her nickname "Perdita" for her role as Perdita (heroine of Shakespeare's The Winter's Tale) in 1779, and was the first public mistress of King George IV while he was still Prince of Wales.

Grace Dalrymple Elliott (c. 1754 – 16 May 1823) was a Scottish courtesan, writer and spy resident in Paris during the French Revolution. She was an eyewitness to events detailed in her memoirs, Journal of my life during the French Revolution (Ma Vie sous la Révolution) published posthumously in 1859. She was mistress, first to the future George IV, by whom she is said to have borne an illegitimate daughter, and then to the Duke of Orléans. Elliott trafficked correspondence and helped condemned Royalists and members of the French nobility escape from the First French Republic during the Reign of Terror. She was arrested several times but managed to avoid the guillotine, and was released following the military coup that ended the Terror and resulted in the execution of Robespierre.

In the acclaimed but widely controversial 2001 film adaptation of her memoirs by French New Wave director Éric Rohmer as The Lady and the Duke, Grace Elliot was played by English actress Lucy Russell.
