She is almost certainly a member of the Manners family of Haddon Hall and Belvoir Castle; the ancient family of Manners is headed by the 11th Duke of Rutland.

Unusually, for this period, the sitter wears a large diamond hair clip. (Until the 19th c. all diamonds were flat or table cut and thus appear as black gems in portraiture).
A well painted portrait, very strongly influenced by Kneller, and absolutely typical of its time.

SIR GODFREY KNELLER (1646-1723) was the most distinguished painter of baroque portraits in England.
Born in Lubeck, he trained with Bol and Rembrandt, coming to London in 1676.
By 1679 he had painted the King and remained the most famous and successful portrait painter in England until his death.

In 1688 he was made Principal Painter to the King and was knighted in 1692 and a made a baronet in 1715.
His style had a profound influence on British portraiture and a large number of artists, some very talented in their own right, emulated his fashionable style.
