Earl Coningsby was a title in the Peerage of Great Britain.
She had no surviving male issue and the titles became extinct on her death in 1761.
Lady Frances Coningsby, younger daughter of the first Earl by his second marriage, married Sir Charles Hanbury Williams.
The character of Lady Jane Coningsby in the children's mystery novels, the Lady Grace Mysteries, is probably based on Jane, the daughter of Humphrey Coningsby (1516-1559) of Hampton Court in Herefordshire and his wife, Anne, sister of Sir Francis Englefield of Englefield House in Berkshire; and eventual wife of William Boughton (1543-1596) of Little Lawford at Newbold-on-Avon in Warwickshire.
She appears as a maid of honour to Queen Elizabeth I and friend to the main character, Lady Grace Cavendish.
