Evelyn's Diary. 17 Oct 1671. My [her future husband] Lord Henry Howard (age 43) coming this night to visit my Lord Chamberlain, and staying a day, would needs have me go with him to Norwich, Norfolk [Map], promising to convey me back, after a day or two; this, as I could not refuse, I was not hard to be pursuaded to, having a desire to see that famous scholar and physician, Dr. T. Browne (age 65), author of the Religio Medici and Vulgar Errors, now lately knighted. Thither, then, went my Lord and I alone, in his flying chariot with six horses; and by the way, discoursing with me of several of his concerns, he acquainted me of his going to marry his eldest son (age 43) to one of the King's (age 41) natural daughters [Note. Either Anne Fitzroy Countess Sussex (age 10) or Charlotte Fitzroy Countess Lichfield (age 7).], by the Duchess of Cleveland (age 30); by which he reckoned he should come into mighty favor. He also told me that, though he kept that idle creature, Mrs. B-- [Note. Jane Bickerton Duchess Norfolk (age 28)], and would leave £200 a year to the son [Note. Henry Howard and Jane Bickerton had three sons; not clear which is being referred to since the eldest may have died and the reference may be to a surviving son.] he had by her, he would never marry her, and that the King (age 41) himself had cautioned him against it. All the world knows how he kept his promise [Note. meaning he didn't keep his promise since Henry Howard did marry Jane Bickerton - this a case of John Evelyn writing his diary retrospectively?], and I was sorry at heart to hear what now he confessed to me; and that a person and a family which I so much honored for the sake of that noble and illustrious friend of mine, his grandfather, should dishonor and pollute them both with those base and vicious courses he of late had taken since the death of Sir Samuel Tuke (age 56), and that of his own virtuous lady (my Lady Anne Somerset, sister to the Marquis); who, while they lived, preserved this gentleman by their example and advice from those many extravagances that impaired both his fortune and reputation.

Evelyn's Diary. 23 Jan 1678. Dined with the [her husband] Duke of Norfolk (age 49), being the first time I had seen him since the death of his [her brother-in-law] elder brother, who died at Padua in Italy, where he had resided above thirty years. The Duke (age 49) had now newly declared his marriage to his concubine (age 35), whom he promised me he never would marry. I went with him to see the Duke of Buckingham (age 49), thence to my Lord Sunderland (age 36), now Secretary of State, to show him that rare piece of Vosterman's (son of old Vosterman), which was a view, or landscape of my Lord's palace, etc., at Althorpe [Map] in Northamptonshire.

Evelyn's Diary. 25 Aug 1678. There was at Weybridge the Duchess of Norfolk (age 35), [her step-son] Lord Thomas Howard (age 21) (a worthy and virtuous gentleman, with whom my son (age 23) was sometime bred in Arundel House [Map]), who was newly come from Rome, where he had been some time; also one of the Duke's daughters, by his first lady. My [her husband] Lord (age 50) leading me about the house made no scruple of showing me all the hiding places for the Popish priests, and where they said mass, for he was no bigoted Papist. He told me he never trusted them with any secret, and used Protestants only in all businesses of importance.
