Lucy Walter was born into a family of middling Welsh gentry. She was the daughter of William Walter of Roch Castle, near Haverfordwest, Pembrokeshire, and his wife Elizabeth, daughter of John Prothero and niece of John Vaughan, 1st Earl of Carbery. She is said to have been born at Roch Castle in 1630. In 1644, the castle having been taken and destroyed by the parliamentary forces, she sought refuge in London, whence she took shipping for The Hague. Algernon Sidney told James, Duke of York, that he had given fifty gold pieces for her, but, having to join his regiment hastily, had missed his bargain. His brother, Colonel Robert Sidney secured the prize, but did not retain it long. During the summer of 1648 this "private Welshwoman", as Clarendon calls her, "of no good fame, but handsome", captivated the then Prince of Wales, who was at The Hague for a short while about this time. He was only eighteen, and she is often spoken of as his first mistress, but there seems good reason to suppose that he had a tryst as early as 1646, James II admits Lucy's good looks, adding that, though she had not much wit, she had a great deal of that sort of cunning which those of her profession usually have. On 9 April 1649, Lucy's son, James, the future Duke of Monmouth, was born in Rotterdam and recognised by Charles as his natural son. In August 1649 the respectable John Evelyn travelled with Lucy in Lord Wilmot's coach from Paris to Saint-Germain-en-Laye, and speaks of her as "a brown, beautiful, bold but insipid creature". During July and August 1649 she was with Charles at Paris and Saint-Germain, and she may have accompanied him to Jerseyin September. In June 1650 Charles left her at The Hague upon embarkation for Scotland. During his absence Lucy had an affair with Theobald, 2nd Viscount Taaffe, with whom she had a daughter, Mary. After his defeat at the Battle of Worcester in late 1651, Charles escaped from England and returned to the Continent. He made it clear to Lucy that their relationship was ended. At first she attempted to persuade Dr John Cosin that she was a convert, but that did not work. For about four years, she was involved in one scandal after another, causing so much embarrassment to the royal court in exile, that early in 1656 when she was in Cologne, the king's friends, by a promise of a pension of five thousand livres, persuaded her to return with her children to England. She sailed from Flushing and obtained lodgings in London over a barber's shop near Somerset House. The Lord Protector's intelligence department promptly reported her as a suspected spy, and at the close of June 1656 she and her maid, Ann Hill, were arrested and sent to the Tower of London. On 16 July, after examination, she was discharged and ordered to be deported back to the Low Countries. Once back on the Continent, she travelled to Brussels and resumed her extravagant lifestyle. Her attempt to use her son as a means of influencing Charles failed. However, after the court party botched an attempt to kidnap the boy, she was persuaded in March 1658 to hand him over to a royal tutor. In September of the same year—after making a general confession to John Cosin—she died in Paris probably of venereal disease and was buried there.
Children
She is known to have had two children:
James, born at Rotterdam on 9 April 1649, who was on 14 February 1663 created Duke of Monmouth.
Exclusion Bill and allegations of marriage to Charles II
Between 1673 and 1680 a legend was prepared and industriously circulated by the country party to the effect that Charles had legally married Lucy Walter. It was asseverated in course of time that the contract of marriage was preserved in a black box in the possession of Sir Gilbert Gerard, son-in-law of John Cosin. In a novel which had a wide circulation it was the designing Prince of Purdino who advised his brother, King Conradus of Otenia, to marry the beautiful "Lucilious", but, to avoid disgusting the Otenians, to do so with the greatest privacy imaginable, and in the presence of but two witnesses, himself and the priest. Sir Gilbert Gerard, summoned before an extraordinary meeting of the Privy Council convened by King Charles II, stated that he knew nothing whatever of such a marriage contract; and the King issued three declarations in denial of the marriage. One of these declarations, signed by sixteen Privy Councillors, was entered in the council book and registered in chancery.
