Samuel Pepys' Diary 1667 September 16. 16 Sep 1667. Up, and several come to me, among others Mr. Yeabsly of Plymouth, Devon [Map], to discourse about their matters touching Tangier, and by and by Sir H. Cholmly (age 35), who was with me a good while; who tells me that the Duke of York's (age 33) child is christened, the Duke of Albemarle (age 58) and the Marquis of Worcester (age 38) godfathers, and my Lady Suffolke (age 45) godmother; and they have named it Edgar, which is a brave name.

Survey London Volume 4 Chelsea Part II. In the account in the Architectural Review (May, 1911) I have summarised the later history of the house as follows:-"After the great house had been occupied during the Commonwealth by the Parliamentary Commissioners, Sir Bulstrode Whitlocke and John Lisle, the second Duke of Buckingham regained possession. Lost to him, through his debts, the house ultimately passed (1674) into the hands of the trustees for George Digby, Earl of Bristol, and his Countess sold it in 1682 to Henry, Marquess of Worcester, afterwards Duke of Beaufort, the house remaining in his family until 1720. It was during this period, about the year 1699, that Kip's beautiful view of the mansion - now called Beaufort House - was published, a priceless record of the property, so ruthlessly defaced and destroyed by Sir Hans Sloane after he purchased it in 1737. Mr. Randall Davies, whom I have followed in the account of the occupants of the house, has printed the interesting conveyance of the property to Sloane, and if its description is carefully collated with the information in Kip's view, one is struck by the wonderful accuracy of the latter. Here is the great house as shown by Thorpe, its lodges and its forecourts, the wharf, with its brick towers east and west, the orchard and 'one garden environed with brick walls … and a terrace on the north end, with a banqueting house on the east end of the terrace,' as well as 'one great garden … extending from the terrace and banqueting house into the highway on the north.' This banqueting house is alike in detail to the sketch of 'a summer house, Chelsea,' in the Smithson collection of seventeenth-century drawings, now in the possession of Colonel Coke. But valuable as is the representation of the great house, the print has much more information to give us. The great park is there shown in all its original beauty; the Duke of Beaufort's stables and yard, since converted into the historic chapel and burying ground of the Moravians is to the west; and nearer the river the beautiful Jacobean house of Sir Arthur Gorges (our sole evidence of its character and design) and the house and gardens of the Earls of Lindsey. And to the east, below the wide area of Dovecote Close, laid out as a huge kitchen garden, are the fine pleasure grounds of Danvers House, which had been destroyed but three years before the drawing was published.".
