Walter, Lucy, 1630?–1658, mistress (1648–50) of Charles II of England during his exile in Holland and France. She was the mother by him of James Scott, duke of Monmouth, whom the Whigs supported as heir to the throne in their attempt to exclude James, duke of York (later James II), from the succession. It was rumored at that time that Charles had actually married Lucy and that proof of the marriage was contained in a mysterious black box. Charles always denied the report. Lucy herself was a courtesan before and after her connection with Charles. She was arrested (1656) in London as a spy but was released and sent abroad. She died in Paris.
