Allardyce, whose father belonged to a cadet branch of an old Kincardineshire family, was admitted an infant burgess of Aberdeen in 1745 and went early in life to Jamaica. As well as fathering an illegitimate daughter, whom he remembered in his will, he became ‘very rich’ through his activities in the slave trade. It was later said of him that he had ‘sold about as many blackmen as there are white in his native city’.
Allardyce was presumably the man of that name predicted to be the ministerial nominee for a vacancy for East Looe in January 1790; nothing came of it. He was returned unopposed for Aberdeen Burghs on the death of the sitting Member in 1792, with the backing of Henry Dundas, and retained the seat unchallenged in 1796. The following year there was talk of his standing for the vacant county seat, but he did not do so.
If any man has a more natural claim ... than myself, let it be given to him. If any man more strictly attends his duty in Parliament than myself ... [or] gives a stronger support to administration ... let it be given to him. If any man at the India House ... [or] the Bank of England supports the true interests of administration more than myself, let it be given to him. If any man in his provincial capacity supports the interests of administration more than myself, let it be given to him. But I have the vanity to think you will find no such man.
