Sidney Parker, main male character of the Sanditon book is Jane Austen's last hero. An elegant, witty man, close to his family, kind with excellent manners (as JA describes him in the book) he would have been destined for a wonderful happy ending with the heroine of the book  Charlotte Heywood if Jane Austen could have finished writing it.

With this petition we ask for a worthy happy ending for Charlotte and Sidney (with a film or a TV series) as it happened for Mr Darcy and Elizabeth, for Captain Wentworth and Anne Eliot and all the characters in Jane Austen's works.

Sidney Parker was about seven or eight and twenty, very good-looking, with a decided air of ease and fashion, and a lively countenance. - This adventure afforded agreeable discussion for some time. Mrs. Parker entered into all her husband's joy on the occasion, and exulted in the credit which Sidney's arrival would give to the place. (Chapter 12)

… single and independent … by collateral inheritance, quite as well provided for as himself... (Chapter 2)

The manners of the Parkers were always pleasant among themselves - and it was a very friendly meeting between Sidney and his sister in law, who was most kindly taking it for granted that he was on his way to Trafalgar House. (Chapter 12)

… and a very well-bred bow and proper address to Miss Heywood on her being named to him. (Chapter 12)

There is someone in most families privileged by superior abilities or spirits to say anything. - In ours, it is Sidney; who is a very clever young man, and with great powers of pleasing. - He lives too much in the world to be settled; that is his only fault. - He is here and there and every where. I wish we may get him to Sanditon. I should like to have you acquainted with him. - And it would be a fine thing for the place! - Such a young man as Sidney, with his neat equipage and fashionable air.  (Chapter 4)
