Linwood was an associate in business of Brice Fisher, and over his affair dropped out of the directorate of the East India Company. He was also a partner of Fisher and of Sir William Baker in the ‘Hobcaw Barony’ in South Carolina;
Linwood’s chief connexions among politicians before entering the House were with Henry Fox and John Calcraft. He was also a friend of Richard Rigby.
In 1761 Linwood was returned on Fox’s interest for Stockbridge; was marked in Bute’s list as ‘Fox’ and ‘pro’; and was included in Fox’s list of Members favourable to the peace preliminaries, though with a query before his name (probably an indication that he had not then arrived in London). Throughout his parliamentary career he seems to have voted with whatever Administration was in office, and never appears in an Opposition list, not even over the repeal of the Stamp Act.
Linwood was a Government contractor. On 22 Dec. 1761 he offered to remit money for the troops at Belle Isle; in April 1762 he obtained together with Tierney and George Amyand a contract for provisioning troops in Portugal; in June 1763 for remitting money to Minorca, which he still held in 1767.
On 10 Nov. 1767 Sir William Musgrave, stepfather of the young Lord Carlisle, who was then travelling in France, wrote to him about Morpeth: he had settled with the Duke of Grafton that Linwood should stand; ‘and as you may be curious to know some particulars of him, I can only inform you that I believe he was formerly a very considerable merchant in the city, but having acquired a very large fortune he has quitted business, and lives in Spring Gardens in a very genteel manner’. On 11 Dec.: he is informed that Peter Beckford (the other candidate) and Linwood ‘have been through the town of Morpeth, and have met with as much success as could be expected’. On 22 Dec. Musgrave still hoped ‘that both candidates will be chosen’ on Carlisle’s interest. But in the end, with Grafton’s advice, a compromise was concluded which left Carlisle one seat only;
There is no record of his having spoken in the House. He died 2 May 1773.
