Mosman's attractive portrait of the eldest son of the Murrays of Cringletie in Peebleshire was painted in about 1730. While Mosman's career took him to Italy and the studio of the Roman painter Francesco Imperiale, Alexander Murray entered the army spending much of his time in Canada. He was at Quebec with General Wolfe in 1759 and was the officer who took possession of the city and received its keys from the defeated French. Murray's second son was christened James Wolfe Murray after his godfather. General Wolfe's wish that his name might remain in the family of his godson has been honoured by his descendants, the Wolfe Murray family.
