Evelyn's Diary. 09 Jun 1658. I went to see the Earl of Northumberland's (age 55) pictures, whereof that of the Venetian Senators was one of the best of Titian's and another of Andrea del Sarto, viz, a Madonna, Christ, St. John, and an Old Woman; a St. Catherine of Da Vinci, with divers portraits of Vandyck; a Nativity of Georgioni; the last of our blessed Kings (Charles I.), and the Duke of York, by Lely (age 39), a Rosary by the famous Jesuits of Brussels, and several more. This was in Suffolk House, Suffolk Street: the new front toward the gardens is tolerable, were it not drowned by a too massy and clumsy pair of stairs of stone, without any neat invention.

Pepy's Diary. 30 Jun 1660. By times to Sir R. Fanshawe (age 52) to draw up the preamble to my Lord's Patent. So to my Lord, and with him to White Hall, where I saw a great many fine antique heads of marble, that my Lord Northumberland (age 57) had given the King. Here meeting with Mr. De Cretz, he looked over many of the pieces, in the gallery with me and told me [by] whose hands they were, with great pleasure. Dined at home and Mr. Hawly with me upon six of my pigeons, which my wife has resolved to kill here. This day came Will¹, my boy, to me; the wench continuing lame, so that my wife could not be longer without somebody to help her. In the afternoon with Sir Edward Walker, at his lodgings by St. Giles Church, for my Lord's pedigree, and carried it to Sir R. Fanshawe. To Mr. Crew's (age 62), and there took money and paid Mrs. Anne, Mrs. Jemima's maid, off quite, and so she went away and another came to her. To White Hall with Mr. Moore, where I met with a letter from Mr. Turner, offering me £150 to be joined with me in my patent, and to advise me how to improve the advantage of my place, and to keep off Barlow. To my Lord's till late at night, and so home.

Evelyn's Diary. 06 Sep 1680. I dined with Sir Stephen Fox (age 53), now one of the Lords Commissioners of the Treasury. This gentleman came first a poor boy from the choir of Salisbury, then he was taken notice of by Bishop Duppa, and afterward waited on my [his brother] Lord Percy (brother to Algernon, Earl of Northumberland), who procured for him an inferior place among the clerks of the kitchen and Greencloth side, where he was found so humble, diligent, industrious, and prudent in his behavior, that his Majesty being in exile, and Mr. Fox waiting, both the King (age 50) and Lords about him frequently employed him about their affairs, and trusted him both with receiving and paying the little money they had. Returning with his Majesty (age 50) to England, after great want and great sufferings, his Majesty (age 50) found him so honest and industrious, and withal so capable and ready, that, being advanced from clerk of the kitchen to that of the Greencloth, he procured to be paymaster of the whole army, and by his dexterity and punctual dealing he obtained such credit among the bankers, that he was in a short time able to borrow vast sums of them upon any exigence. The continual turning thus of money, and the soldiers' moderate allowance to him for keeping touch with them, did so enrich him, that he is believed to be worth at least £200,000, honestly got and unenvied; which is next to a miracle. With all this he continues as humble and ready to do a courtesy as ever he was.

Evelyn's Diary. 15 Nov 1681. I dined with the [his son-in-law] Earl of Essex (age 49) who, after dinner in his study, where we were alone, related to me how much he had been scandalized and injured in the report of his being privy to the marriage of his [his daughter] Lady's (age 45) niece (age 14), the rich young widow of the late Lord Ogle, sole daughter of the Earl of Northumberland; showing me a letter of Mr. Thynn's (age 33), excusing himself for not communicating his marriage to his Lordship (age 49). He acquainted me also with the whole story of that unfortunate lady being betrayed by her [his former wife] grandmother, the Countess of Northumberland (age 58), and Colonel Bret, for money; and that though, upon the importunity of the Duke of Monmouth (age 32), he had delivered to the grandmother a particular of the jointure which Mr. Thynn (age 33) pretended he would settle on the lady, yet he totally discouraged the proceeding as by no means a competent match for one that both by birth and fortune might have pretended to the greatest prince in Christendom; that he also proposed the Earl of Kingston (age 21), or the Lord Cranburn, but was by no means for Mr. Thynn (age 33).

Evelyn's Diary. 11 Mar 1705. An exceedingly dry season. Great loss by fire, burning the outhouses and famous stable of the Earl of Nottingham (age 57), at Burleigh [Rutlandshire], full of rich goods and furniture, by the carelessness of a servant. A little before, the same happened at Lord Pembroke's (age 49), at Wilton. The old [his former wife] Countess of Northumberland (age 82), Dowager of Algernon Percy, Admiral of the fleet to King Charles I., died in the 83d year of her age. She was sister to the [his former brother-in-law] Earl of Suffolk, and left a great estate, her jointure to descend to the Duke of Somerset (age 42).
