No example of Farquhar's hand is known to survive, neither have any authoritative manuscripts of any of his works been recorded in modern times.
The extant documents most closely related to the dramatist are a brief series of undated letters and petitions written c.1707-10 by or on behalf of his widow, Margaret. Three are addressed to the Secretary of State, Robert Harley, begging him to help her get a pension from the Queen. These are among the Harley Papers in the Duke of Portland's muniments formerly at Welbeck Abbey and now in the British Library. One, written according to her subscription in my sons hand
, is Add. MS 70225, [unnumbered page]. Another, written in a different hand, is Add. MS 70024, ff. 105r-7v. Here she is found commenting on her distressed condition and remarking: I neuer yet receiu'd a farthing from her matie; except ten Guinneys by ye hands of ye Dutchess of Devonshire, vpon ye presentation of my husbands poem
. A third letter, in yet another style of hand, is Add. MS 70024, f. 108r-v. Here she refers to Harley's Generous favors in return of my book by my Daughter
, asks him to further her petition to the Queen by reading over these papers wch are ye coppys of ye Originalls wch I have by me
and refers again to having received ten guineas from the Queen for ye book wch you did me ye honr to receive
.
In another division of the Harley Papers, which was at Welbeck Abbey in 1937 but whose present whereabouts is unclear, two of Margaret Farquhar's original petitions to Queen Anne were to be found, accompanied by three certificates concerning Farquhar's military service, signed by the Duke of Ormonde (Lord Lieutenant of Ireland), the Duke of Bolton, and Farquhar's regimental commander, the Earl of Orrery. For these, and related documents, see the discussion and partial transcript in James R. Sutherland, a Voluntier at ye Battle of ye Boyn
[in 1690] and Lieutenant of Grenadiers in Orrery's Regiment of Foot [in 1704-5]), while Orrery, in his certificate of support, interestingly describes Farquhar as a Person of great Ingenuity
(a phrase reminiscent of the first collected edition of
Yet another recorded letter by Margaret Farquhar, addressed to the Hon. Mr Vice-Chamberlain and complaining of her inadequate receipts from the playhouse, is cited in Stonehill (I, xxxii). The original letter was offered for sale in Dobell's catalogue No. 26 (1937), as item 117, where more of the text is quoted, including her statement: the players I understand usually allowed for their benefit play but still I hope thro your powerfull mediation it may be reduced to a much less sume, for ye chief actors I presume may be easily prevaild to quett their own charges upon Mr. Farquhars account who has bin so serviceable to them
.
In 1710, Farquhar's widow published his ye book
— my husbands poem
— which, according to her letters to Harley, she presented to Queen Anne, although her dedication in the printed edition is to Charles Mordaunt, Earl of Peterborough. The poem was found, she says, among my dear Deceas'd Husband's Writings
, the Original
being produc'd under his own Hand
(Stonehill, II, 363-4).
Of George Farquhar's own correspondence, a number of texts are preserved only in such (less than totally reliable) publications as 1702
[i.e. 1701]), for which see Stonehill, II, 217-343. The addressees of the dedicatory epistle of Farquhar's various published works include Peregrine Osborne, Marquess of Carmarthen (and later second Duke of Leeds); Sir Roger Mostyn, Bt; Arnold Joost Van Keppel, first Earl of Albemarle; Richard Tighe; Henry Brett; Samuel Bagshaw; and Edmond Chaloner.
