The story of Sidnee
Sir Philip Sidney, poet and soldier, was mortally wounded at Zutphen in 1586; according to the account of his friend Fulke Greville, when water was brought to him he passed it to a dying soldier with the words 'Thy necessity is yet greater than mine'. In 1859 Charles Dickens ended A Tale of Two Cities with Sydney Carton taking the place of another man at the guillotine: 'It is a far, far better thing that I do, than I have ever done.' The surname became a boy's first name, and in the later twentieth century it crossed to girls; Sidnee, with its double e, is one of the spellings made for daughters.
