Dickinson seems to have been a City attorney—Dupplin in 1754 listed him as a practising lawyer. The Duke of Bedford wrote from Woburn on 5 Aug. 1753 to his nephew, the young Duke of Bridgwater, then on his Grand Tour: ‘As he [Dickinson] is one for whom I have the greatest esteem and a near neighbour to me in this county, I was determined to bring him into Parliament and did intend him for the town of Bedford, but as our plan is altered there I take the liberty to recommend him to you for Brackley.’
When on 20 Aug. 1756, after the loss of Minorca, the City address was presented to the King asking for ‘the authors of our late losses and disappointments to be inquired into and punished’, which the King told them would be done,
At a meeting of the livery at Guildhall, 4 Mar. 1761, Dickinson was ‘put in nomination’ for the general election, but failed to receive sufficient support.
A bill had come to us from the Lords about certain trust lands at Tavistock, relating to the Duke of Bedford’s affairs, and which he had brought in. There was a clause in it to declare that those lands were to convey no right of voting in that borough. This got among the Commons as a breach of their privileges, and the bill had certainly been flung out had not Alderman Dickinson moved that it be withdrawn. He was mistaken in the manner of doing this, by beginning that he had authority from a noble duke, etc. We want no authority from noble dukes, nor from those greater than dukes, to empower us to do our acts.
Similarly on 23 Mar., over ‘excepting Covent Garden Market out of the fish bill’—‘The commitment of the bill’, wrote Dickinson to the Duke, ‘I have got put off till to-morrow and shall be glad to receive your Grace’s directions thereon that I may prevent opposition.’
On one occasion Dickinson stood up to the Duke—for a short while. Lord Tavistock, a friend of Dickinson’s son, John Marshe Dickinson, had obtained for young Dickinson the office of superintendent of his Majesty’s gardens.
In the House Dickinson naturally supported the peace treaty negotiated by Bedford, and exerted himself on the side of the Grenville-Bedford Government. When he died, 6 Feb. 1765, Mary Townshend wrote to her uncle, George Selwyn, that he ‘died of general warrants’.
