Pepy's Diary. 27 Oct 1662. He told me what great faction there is at Court; and above all, what is whispered, that young Crofts (age 13) is lawful son to the King (age 32), the King (age 32) being married to his mother¹. How true this is, God knows; but I believe the Duke of York (age 29) will not be fooled in this of three crowns.

Note 1. There has been much confusion as to the name and parentage of Charles's mistress. Lucy Walter was the daughter of William Walter of Roch Castle, co. Pembroke, and Mr. S. Steinman, in his "Althorp Memoirs" (privately printed, 1869), sets out her pedigree, which is a good one. Roch Castle was taken and burnt by the Parliamentary forces in 1644, and Lucy was in London in 1648, where she made the acquaintance of [his brother] Colonel Algernon Sidney (age 39). She then fell into the possession of his brother, Colonel Robert Sidney². In September of this same year she was taken up by Charles, Prince of Wales. Charles terminated his connection with her on October 30th, 1651, and she died in 1658, as appears by a document (administration entry in the Register of the Prerogative Court) met with by the late Colonel Chester. William Erskine, who had served Charles as cupbearer in his wanderings, and was appointed Master of the Charterhouse in December, 1677, had the care of Lucy Walter, and buried her in Paris. He declared that the King (age 32) never had any intention of marrying her, and she did not deserve it. Thomas Ross, the tutor of her son, put the idea of this claim into his head, and asked Dr. Cosin to certify to a marriage. In consequence of this he was removed from his office, and Lord Crofts (age 51) took his place (Steinman's "Althorp Memoirs"). Lucy Walter took the name of Barlow during her wanderings.

Note 2. TT. Not clear who Colonel Robert Sidney is since Algernon Sidney (age 39) didn't have a brother called Robert. Algernon's brothers were [his brother] Philip Sidney 3rd Earl of Leicester (age 43) and Henry Sidney 1st Earl Romney (age 21).

Pepy's Diary. 09 Jan 1666. After dinner Pierce and I up to my chamber, where he tells me how a great difference hath been between the Duke (age 32) and Duchesse (age 28), he suspecting her to be naught with Mr. Sidney (age 24)¹. But some way or other the matter is made up; but he was banished the Court, and the Duke for many days did not speak to the Duchesse at all. He tells me that my Lord Sandwich (age 40) is lost there at Court, though the King (age 35) is particularly his friend. But people do speak every where slightly of him; which is a sad story to me, but I hope it may be better again. And that Sir G. Carteret (age 56) is neglected, and hath great enemies at work against him. That matters must needs go bad, while all the town, and every boy in the streete, openly cries, "the King (age 35) cannot go away till my Baroness Castlemaine's (age 25) be ready to come along with him"; she being lately put to bed And that he visits her and Mrs. Stewart (age 18) every morning before he eats his breakfast. All this put together makes me very sad, but yet I hope I shall do pretty well among them for all this, by my not meddling with either of their matters. He and Ferrers gone I paid uncle Thomas his last quarter's money, and then comes Mr. Gawden and he and I talked above stairs together a good while about his business, and to my great joy got him to declare that of the £500 he did give me the other day, none of it was for my Treasurershipp for Tangier (I first telling him how matters stand between Povy (age 52) and I, that he was to have half of whatever was coming to me by that office), and that he will gratify me at 2 per cent. for that when he next receives any money. So there is £80 due to me more than I thought of. He gone I with a glad heart to the office to write, my letters and so home to supper and bed, my wife mighty full of her worke she hath to do in furnishing her bedchamber.

Note 1. "This Duchess (age 28) was Chancellor Hyde's (age 56) daughter, and she was a very handsome woman, and had a great deal of wit; therefore it was not without reason that Mr. Sydney (age 24), the handsomest youth of his time, of the Duke's bedchamber, was so much in love with her, as appeared to us all, and the Duchess not unkind to him, but very innocently. He was afterwards banished the Court for another reason, as was reported" (Sir John Reresby's Memoirs, August 5th, 1664, ed. Cartwright, pp. 64,65). "'How could the Duke of York (age 32) make my mother a Papist?' said the Princess Mary to Dr. Bumet. 'The Duke caught a man in bed with her,' said the Doctor, 'and then had power to make her do anything.' The Prince, who sat by the fire, said, 'Pray, madam, ask the Doctor a few more questions'" (Spence's "Anecdotes", ed. Singer, 329).
