"Her husband, Roger Palmer, to whom she was married at the age of eighteen, appears as a sensitive and somewhat gloomy figure, his depression hardly surprising in view of the outrageous cuckolding by his young wife. In the autumn of 1661 he accepted the title of Earl of Castlemaine, with the further humiliation that its inheritance was limited to 'heirs of his body gotten on Barbara Palmer his now wife' - making the source of the honour quite clear. Shortly after the birth of Barbara's second child [Charles (1662-1730] by the King in June 1662, the new Earl separated from her, having first caused the boy to be baptized a Catholic. Barbara was to become a Catholic herself. But at the time she had the baby ostentatiously rechristened in the Anglican Church." (in: Antonia Fraser: King Charles II, id., p. 210).
Barbara Villiers im Jahr 1662: "'Strange,' remarks Pepys, 'how the King is bewitched to this pretty Castlemaine [Barbara Villiers]; her interest at Court is now greater than the Queen’s [Katharina von Braganza]; and she, with Sir Charles Barkeley and Sir H. Bennett, both of whom she hath brought in, hath more influence with the King than any one else at Court.' … 'He sups, at least, four times every week with my Lady Castlemaine, and most often stays till the morning with her, and goes home through the garden all alone, privately, and that so as the very sentries take notice of it and speak of it.' The public loudly condemned these shameful doings of the King and his paramour. But Charles disregarded the clamours of the people, and carried her with him to Windsor, where, with his profligate Court, he celebrated the festival of St. George with unusual magnificence, in honour of the Duke of Monmouth’s marriage with Lady Anne Scott, heiress of Buccleugh. 'I did hear,' says Pepys, 'that the Queen is much grieved of late at the King’s neglecting her, he not having supped with her this quarter of a year. She was at Windsor, at the St. George’s feast there [April the twenty-third, 1663], and the Duke of Monmouth, dancing with her, with his hat in his hand, the King came in and kissed him, and made him put on his hat, which everybody took notice of; indeed, Monmouth is in so great splendour at Court, and so dandled by the King, that some doubt that if the King should have no child by the Queen, which there is yet no appearance of, whether he would not be acknowledged for a lawful son.'" (in: Francis Lancelott: The Queens of England and their Times, Volume II, id., pp. 718-719).
