WALTER, LUCY (c. 1630-1658), mistress of the English king Charles II. and mother of the duke of Monmouth (q.v.), was born at Roch Castle, near Haverfordwest. Her home having been captured and burned by the Parliamentary forces in 1644, Lucy Walter found shelter first in London and then at The Hague. There, in 1648, she met Charles, possibly renewing an earlier acquaintance. Their intimacy lasted with intervals till the autumn of 1651, and Charles claimed the paternity of a child born in 1649, whom he subsequently created duke of Monmouth.
