MacQueen’s origins were sufficiently varied: his paternal grandfather was Rev. Donald MacQueen of Kilmuir, Skye, of whom Dr Johnson spoke so well during his Highland tour. His father, described in 1775 as ‘a young gentleman bred to physic’ was nephew of Macleod, the laird of Raasay, spoke ‘the Gaelic in all its purity’
Thomas Potter MacQueen was bred to the law, called, but never practised, and in Parliament three years before he qualified. Col. John MacLeod was given credit for launching him in public life and so was (Sir) John Osborn,
He aspired, like his great grandfather Thomas Potter in 1758, to a county seat; in 1826 he obtained it, but it proved his ruin, for he was involved at the ensuing election in a contest with the Russells that swallowed up his inheritance of the year before and drove him to New South Wales. Ironically, in 1820, claiming to be the Member of Parliament most conversant with South African affairs, he had been interested in promoting Scottish emigration thither; better still, on 5 Aug. 1820 he applied to government to be governor of New South Wales, claiming to have an ‘intimate knowledge’ of its history. Among other qualifications, he mentioned that ‘from the application of chemistry to various important articles of manufacture I have produced samples of hemp, flax, cotton, silk—animal and vegetable of a quality which has excited the wonder of the first manufacturers of this country’.
