Marjoribanks’s maternal grandfather Archibald Stewart, Member for Edinburgh, 1741-7, and his son John Stewart, Member for Arundel, 1771-4, were in business in London as wine merchants, with premises in Buckingham Street, Strand. By 1768 Archibald Paxton who, like Marjoribanks and Stewart, came from a Berwickshire family, was operating a similar but apparently separate enterprise from the same address, and he took over the whole concern after the deaths of the Stewarts in the early 1780s.
At the general election of 1820 Marjoribanks stood for Hythe, where wealthy merchants were popular with the numerically dominant out-voters. A threatened opposition came to nothing and, with the aid of money and East India Company patronage, he made himself virtually impregnable there. ‘I am not a Whig’, he told his kinsman James Loch* on the eve of the election; and at the nomination, according to one report, he said that he
did not hesitate to declare himself favourable to government, but he was not what is called ‘a thick and thin man’. Whenever administration proposed measures, which to his unbiased judgement appeared for the welfare of the country, they should have his support; but measures which he conceived to be of a contrary tendency, he would as firmly oppose; in short, he should look to measures and not to men.

Yet, in marked contrast to the conduct of his eldest brother Sir John Marjoribanks, almost all his known votes in the 1820 Parliament were with the Whig opposition on most major issues, though it was not until 3 May 1823 that he joined Brooks’s Club.
He divided for Catholic relief, 28 Feb. 1821, 1 Mar., 21 Apr., 10 May 1825. He voted routinely for economy, retrenchment and reduced taxation throughout the Parliament, but on 18 June 1821 he joined his brother in siding with ministers against the omission of arrears from the duke of Clarence’s grant. (They were on opposite sides over the duke of Cumberland’s annuity in 1825.) He was granted three weeks’ leave to attend the Stirlingshire by-election, 17 May 1821. His first known vote for parliamentary reform was on 25 Apr. 1822: thereafter he supported it in the divisions of 3 June 1822, 20 Feb., 24 Apr., 2 June 1823, 26 Feb. 1824, 13, 27 Apr. 1826. Marjoribanks, of whom James Abercromby* wrote in 1824 that he had ‘a very odd temper, which makes it difficult to deal with him’, was one of the few mercantile Members to vote in the ministerial majority for the restriction of bank note circulation, 13 Feb. 1826.
He was unopposed at Hythe at the general election of 1826, when he boasted of his ‘independence’.
When Marjoribanks and his third cousin John Loch, chairman of the East India Company, sought re-election for Hythe in 1830, they encountered an attempt to open the borough. They were returned in defiance of it, and survived a subsequent petition.
Now though Mr. Marjoribanks is a Whig and has as yet voted against us, yet his Whiggery is very much modified (I think) of late, and if he chooses to come forward and ask this as a favour, it would perhaps (if it be a small favour) be a good thing to give it to him.
He added that Marjoribanks had ‘behaved ... civilly’ when they had considered putting up one of Wellington’s sons for Hythe on a vacancy earlier in the year. Wellington felt ‘some difficulty in acceding to the request’, and no immediate decision was taken. When Marjoribanks renewed the request two weeks later Planta, who had hoped he ‘would have properly understood my silence to him’, asked the duke for his ‘formal orders’. It was decided that Marjoribanks’s recommendation should be duly considered ‘at the proper time’ but that, as there was to be no appointment of pilots that year, the matter ‘must stand over until another’. Nothing seems to have come of it.
At the general election in December 1832 Marjoribanks, who expressed cautious support for the abolition of slavery and, though neither ‘a republican, nor a radical’, said he was ‘ready to vote against and assist in reforming any abuse’, stood for the single seat to which Hythe had been reduced. He beat one of his opponents of 1830 and subsequently took up residence at Cliffe House, Folkestone, which formed part of the enlarged constituency.
