Called "pretty, witty Nell" by Samuel 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. She was the most famous Restoration actress and possessed a prodigious comic talent. Gwyn had two sons by King Charles: Charles Beauclerk (1670–1726); and James Beauclerk (1671–1680). [END]
