Barbara Palmer, 1st Duchess of Cleveland, Countess of Castlemaine, was an English royal mistress of the Villiers family and perhaps the most notorious of the many mistresses of King Charles II of England, by whom she had five children, all of them acknowledged and subsequently ennobled. Barbara was the subject of many portraits, in particular by court painter Sir Peter Lely.

Lady of the Bedchamber is the title of a lady-in-waiting holding the official position of personal attendant on a British queen regnant or queen consort. The position is traditionally held by the wife of a peer. A lady of the bedchamber would give instructions to the women of the bedchamber on what their queen wished them to do, or may carry out those duties herself.
