Sir Frederick Augusta Barnard KCH FRS (1 September 1743 – 27 January 1830) was principal librarian to George III during much of the British King's reign. Barnard developed the library collection systematically, seeking guidance from noted intellectuals including writer and lexicographer Dr. Samuel Johnson.
Frederick Augusta Barnard was the son of John Barnard (†1773), a Gentleman Usher, Quarterly Waiter and Page of the Backstairs to Frederick, Prince of Wales. His mother was Elizabeth Smith, who had married John Barnard at Berwick Street Chapel, St James, Westminster, in 1740/1. Barnard was born 1 September 1743 and was baptised at St James, Westminster, 30 September 1743, and was almost certainly a godson of the Prince and his wife Princess Augusta of Saxe-Coburg.
When Barnard died (1830), The Gentleman's Magazine stated 'He was presumed to be a natural son of Frederick, Prince of Wales', a statement repeated in the same magazine in 1834, repeated in Edward Edwards, Lives of the founders of the British Museum (1870), page 468, and several subsequent reference works, and perpetuated by a descendant, the herald James Arnold Frere, in his The British Monarchy at home (1963), pages 42, 45 and 139.
The claim, not based on any earlier record, seems to have originated in the belief that Barnard was Prince Frederick's son by his mistress Anne Vane, the daughter of Lord Barnard, as has been stated by one genealogist, but since Anne died in 1736, that is not possible. That he was the son of John Barnard is proved by the latter's will, dated 2 April 1772, which quotes the terms of his marriage settlement, dated 26 June 1741, which made provision of £5,000 for his wife if she survived him, and then for her children. The will states 'whereas my late wife has departed this life leaving three children by her body by me (viz) the said Elizabeth Barnard and Frederick Augusta Barnard and Mary Barnard now all living". The will further mentions related orders of the Court of Chancery on 24 February 1762 when Samuel Wright was ordered to pay £5,000 to the Accountant General (John's wife Elizabeth having presumably died), and on 28 June 1768 when application was successfully made for the funds, all the children having attained their majorities. The £5,000 was then bequeathed to the three children, the son receiving less than the daughters, he "being happily provided for in his Majesty's service".
