Portsmouth, Louise de Kéroualle, duchess of (1649-1734). Of Breton lineage, Louise de Kéroualle accompanied Henrietta Anne, sister of Charles II, to England in 1670; Charles's despair at Henrietta's sudden death and obvious infatuation with Louise encouraged Louis XIV to send her back to England. She rapidly rose to become ‘the most absolute of the king's mistresses’. Her son by Charles (1672) was created duke of Richmond and she herself made duchess of Portsmouth in 1673. Universally unpopular as Frenchwoman and catholic, she was mercenary, recklessly extravagant, and haughty to inferiors.

(lwēz rənā' də kārūäl') , 1649–1734, French mistress of Charles II of England. She exerted a powerful influence over the king in favor of France—and to her own advantage—from 1671 until his death in 1685. She was made duchess of Portsmouth in 1673 and was the mother by the king of Charles Lennox, duke of Richmond. Hated by many English as a French-Catholic menace, she lived mostly in France after 1685.
