At the court of George I she met Charles II's mistress Louise de Kérouaille, Duchess of Portsmouth, and William III's mistress Elizabeth Hamilton, Countess of Orkney, and exclaimed "God! Who would have thought that we three whores should meet here." At George's coronation in 1714 when the archbishop of Canterbury, Thomas Tenison, ritually asked if the people accepted their new king, Catherine, observing the number of soldiers on duty, asked caustically "Does the old fool think that anyone will say No?" She died at Bath on 26 October 1717. By James II, Lady Dorchester had a daughter, Lady Catherine Darnley, (died 1743), who married James Annesley, 3rd Earl of Anglesey, and after his death married John Sheffield, 1st Duke of Buckingham and Normanby.
