An article in the Kelso Mail, 21 October 1850, outlines the incident recorded by this picture, which was finished in 1859:
'A remarkable feat for a boy of nine years of age was accomplished on Saturday afternoon. Master R. Dennistoun son of Richard Dennistoun, Esq. Pinnaclehill, while fishing in the Tweed hooked a large salmon, and after a very fatiguing run of about two hours and a quarter succeeded in landing it, when it was found to be of the great weight of 21½lbs. The rod with which the fish was captured was a present to the youthful sportsman from the Duchess of Roxburghe, and this was the first occasion on which it had been used'.
Richard Dennistoun (b. 1797) was the son of Richard Dennistoun of Kelvin Grove, Co. Lanark (d. 1834), and Christine, daughter of James Alston, a Glasgow merchant and heir to the estate of Westerton, Co. Dumbarton. He moved from Kelvin Grove to Pinnacle Hill, near Kelso, and in 1839 married Frances Elizabeth, youngest daughter of Thomas Rishton Satterwaite of Lancaster, by whom he had two sons, Richard Campbell (b. 1841) and Francis Douglas (b. 1848), both of whom died unmarried.
