Neither the date of NPG 1421 nor that of the sitter's marriage is available. Kirby's daughter Sarah was born in 1741. Although the pose can be paralleled in a drawing of a seated youth dated by Hayes to the mid 40s,  the fluent handling of NPG 1421 points rather to the early 50s. Gainsborough came to know the Kirbys only when he moved to Ipswich.  He had apparently settled there by June 1752,  having first returned to Sudbury after the death of his father on the 29 October 1748. A stylistic point that seems so far to have escaped attention is the closeness in design and handling between NPG 1421 and Gainsborough's self-portrait with his wife and daughter in the Cholmondeley collection,  usually dated c.1751-52. The composition is almost a mirror of NPG 1421 and the manner of painting the panels of the ladies' skirts almost identical; both may therefore have been painted at about the same time.
Condition: slightly worn; the blue of Kirby's coat may have faded; slight pentimenti along his left arm, and in the dog's head; discoloured varnish and paints partially removed, 1956; the raised left wing of Mrs Kirby's skirt, painted over his coat, may be an alteration in design.
Collections: bought, 1905, from Shepherd Brothers, King Street; presumably painted for the sitter and descended through his grandson, last surviving child of his daughter Sarah, the Rev. Henry Scott Trimmer, Vicar of Heston (d.1859); at Christie's, 17 March 1860, lot 40,  sale of his property, bought in (?) though, in the National Gallery copy of the catalogue, the purchaser is given as the dealer Waters and the sum paid £13.10s; Christie's, 14 March 1903, lot 119, anonymous property (i.e. Trimmer); NG catalogue notes the name Garland as purchaser and the sum paid £42. 0s 0d.
Exhibited: ‘NPE', 1868 (910), lent by the Rev. Kirby Trimmer; 'Bicentenary Memorial Exhibition of Thomas Gainsborough', Ipswich, 1927 (14); 'The Conversation Piece in Georgian England', Kenwood, 1965 (18); 'English painting from Hogarth to Turner', British Council, 1966-67 (31).
Literature: E. Edwards, Anecdotes of Painters, 1808; W.T. Whitley, Thomas Gainsborough, 1915; M. Davies, National Gallery Catalogues, British School, 2nd edition, 1959; J. Hayes, The Drawings of Thomas Gainsborough, 1970.
The only substantial account of Kirby is by Gainsborough who painted him three times: NPG 1421 (above) and two single portraits of which one, stated to be of the mid 1750s,  is in the Victoria and Albert Museum; the other is in the Fitzwilliam.  The latter has been equated with the portrait sent to the Society of Artists exhibition (37) in 1764.  A drawing by Gainsborough 'A landscape with a courtship—portraits of Jos. Kirby and his wife', apparently lot 4 of the 1860 Trimmer sale, is not now known. A profile drawing by P. Falconet signed and dated 1768, collection W.A. Brandt was at Christie's, 12 November 1968, lot 50. It was engraved by D.P. Pariset. The DNB records a portrait by Hogarth in the collection, 1867, of G.C. Handford.
