Eleanor Gwyn (2 February 1650 – 14 November 1687; also spelled Gwynn, Gwynne) was an English stage actress and celebrity figure of the Restoration period. Praised by Samuel Pepys for her comic performances as one of the first actresses on the English stage, she became best known for being a long-time mistress of King Charles II of England (c. April 1668 - 6 February 1685).

Called "pretty, witty Nell" by Pepys, she has been regarded as a living embodiment of the spirit of Restoration England, and has come to be considered a folk heroine, with a story echoing the rags-to-royalty tale of Cinderella. Gwyn had two sons by King Charles: Charles Beauclerk (1670–1726) and James Beauclerk (1671–1680). Charles Beauclerk (pronounced boh-clair) was created Earl of Burford and Duke of St. Albans; Murray de Vere Beauclerk, 14th Duke of St. Albans is her descendant, and the current holder of the duchy.

Early life

The details of Gwyn's background are somewhat obscure. A horoscope in the Ashmolean manuscripts gives her date of birth as 2 February 1650. On the other hand, an account published in The New Monthly Magazine and Humorist in 1838 states that she was born about 1642. The earlier date of birth was asserted without documentation, but various scholars have supported both the earlier and later dates. The eight-year difference between these two possible birth years can offer different readings of what Gwyn achieved during her lifetime.

Nell Gwyn

The obscurity surrounding Gwyn's date of birth parallels numerous other obscurities that run through the course of her life. The information we have about Gwyn is collected from various sources, including the plays she starred in, satirical poetry and pictures, diaries, and letters. As such, much of this information is founded on hearsay, gossip, and rumour, and must therefore be handled with caution.

Nell Gwyn

Her mother Ellen (or a variant, being referred to in her lifetime as "Old Madam", "Madam Gwyn" and "Old Ma Gwyn") was born, according to a monumental inscription, in the parish of St Martin in the Fields, which stretched from Soho and Covent Garden to beyond Mayfair, and is thought to have lived most of her life there in the West End. She is also believed, by most Gwyn biographers, to have been "low-born". Her descendant and biographer Charles Beauclerk calls this conjecture, based solely on what is known of her later life. Madam Gwyn is sometimes said to have had the maiden surname Smith. This appears to be derived from a fragmentary pedigree by Anthony Wood that shows signs of confusion between different Gwyn families and it has not been firmly established. Nell's mother is said to have drowned when she fell into the water at her house near Chelsea. She was buried on 30 July 1679, in her 56th year, at St Martin in the Fields.

Nell Gwyn is reported in a manuscript of 1688 to have been a daughter of "Thos [Thomas] Guine a Capt [captain] of ane antient fammilie in Wales", although the reliability of the statement is doubtful as its author does not seem to have hesitated to create or alter details where the facts were unknown or perhaps unremarkable. There is some suggestion, from a poem dated to 1681, again of doubtful accuracy, that Gwyn's father died at Oxford, perhaps in prison. It has been suggested, based on the pedigree by Anthony Wood, that Gwyn was a granddaughter of Edward or Edmund Gwyn, Canon of Christ Church from 1615 to 1624. However, administration records show that Edmund Gwyn died unmarried. Moreover, Wood did not give a forename for the supposed grandfather of Nell and there are reasons to think that the "Dr ... Gwyn" in the pedigree was intended to be not Edmund Gwyn but rather his brother Matthew. In either case, the available evidence indicates that Nell was not a member of their family.

Gwyn was assigned arms similar to those of the Gwynnes of Llansannor. However, her specific connection to that family, if any, is unknown.
