Caroline of Ansbach, wife of George II of Great Britain, seems to have fit the bill of a great historical cuckquean:
>George Augustus and Caroline had a successful and loving marriage, *though he continued to keep mistresses, as was customary for the time.[23] Caroline was aware of his infidelities; they were well known and he told her about them himself. His two best-known mistresses were Henrietta Howard, later Countess of Suffolk, and, beginning in 1735, Amalie von Wallmoden, Countess of Yarmouth. Howard was one of Caroline's Women of the Bedchamber and became Mistress of the Robes when her husband inherited a peerage in 1731*; she retired in 1734.[24] In contrast with her mother-in-law and husband, Caroline was known for her marital fidelity; she never made any embarrassing scenes nor did she take lovers.[23] She preferred her husband's mistresses to be her ladies-in-waiting so that she could keep a closer eye on them.[25]
