Anne, Countess of Winchelsea, was the Daughter of Sir William Kingsmill, of Sidmonton, in the County of Southampton. — She was Maid of Honour to the second Dutchess of the Duke of York, afterwards K. James II. She married Henage, second Son of the Earl of Winchelsea; who afterwards succeeded to the Title of that Earldom.

A collection of her Poems was printed in 1713, 8vo, containing likewise a Tragedy, called Aristomenes, never acted; and a great Number of her Pieces still continue unpublished. — She died August the 5th, 1720, without Issue; as did the Earl her Husband, September the 30th, 1726.
