Poor Nelly

This is normally given as "Let not poor Nelly starve".

Like many 'famous last words' however, these probably weren't Charles's actual last words. According to The Phrase Finder, while Charles did ask his brother to look after his mistresses, 'including the aforementioned Nell' ... 'His actual dying words, during a lingering demise caused by kidney failure, were: "You must pardon me, gentlemen, for being a most unconscionable time a–dying".'

The brother was presumably Prince James, who would succeed Charles as James II (and James VII of Scotland). Their only other brother – Prince Henry, Duke of Gloucester – had died 25 years previously, in 1660, aged 20.
