Pepy's Diary. 29 Apr 1667. After dinner Sir G. Carteret (age 57) and I alone in his closet an hour or more talking of my Lord Sandwich's (age 41) coming home, which, the peace being likely to be made here, he expects, both for my Lord's sake and his own (whose interest he wants) it will be best for him to be at home, where he will be well received by the King (age 36); he is sure of his service well accepted, though the business of Spain do fall by this peace. He tells me my Lord Arlington (age 49) hath done like a gentleman by him in all things. He says, if my Lord [Sandwich] were here, he were the fittest man to be Lord Treasurer (age 60) of any man in England; and he thinks it might be compassed; for he confesses that the King's matters do suffer through the inability of this man, who is likely to die, and he will propound him to the King (age 36). It will remove him from his place at sea, and the King (age 36) will have a good place to bestow. He says to me, that he could wish, when my Lord comes, that he would think fit to forbear playing, as a thing below him, and which will lessen him, as it do my Lord St. Albans (age 62), in the King's esteem: and as a great secret tells me that he hath made a match for my Lord Hinchingbrooke (age 19) to a daughter (age 22) of my Lord Burlington's (age 54), where there is a great alliance, £10,000 portion; a civil family, and relation to my Chancellor (age 58), whose [her future husband] son (age 5) hath married one of the daughters (age 4); and that my Chancellor (age 58) do take it with very great kindness, so that he do hold himself obliged by it. My Lord Sandwich (age 41) hath referred it to my Lord Crew (age 69), Sir G. Carteret (age 57), and Mr. Montagu (age 49), to end it. My Lord Hinchingbrooke (age 19) and the lady know nothing yet of it. It will, I think, be very happy. Very glad of this discourse, I away mightily pleased with the confidence I have in this family, and so away, took up my wife, who was at her mother's, and so home, where I settled to my chamber about my accounts, both Tangier and private, and up at it till twelve at night, with good success, when news is brought me that there is a great fire in Southwarke [Map]: so we up to the leads, and then I and the boy down to the end of our, lane, and there saw it, it seeming pretty great, but nothing to the fire of London, that it made me think little of it. We could at that distance see an engine play-that is, the water go out, it being moonlight.
Evelyn's Diary. 10 Jun 1673.

Dorothy Howard and Colonel James Graham (age 24) were married in 1675 - may be an example of Evelyn writing his diary retrospectively she being referred to as 'Mrs' although possibly the term was used irrecspective of marriage - see John Evelyn's Diary 1671 October 09]. We went, after dinner, to see the formal and formidable camp on Blackheath, Greenwich [Map], raised to invade Holland; or, as others suspected for another design.
