The letter is dated based on the reference to the tract in the letter.
More's Cheap Repository Tract, 'The Death of Mr Fantom, The Great Reformist, who Departed this Life, March the 20th, 1817'. Ian Haywood gives an overview of the tract, its origins and targets in The Revolution in Popular Literature, p. 92. (Preview on Google Books).
More is perhaps referring here to a publication by Thomas Chalmers: the fifth edition of The Evidence and authority of the Christian Revelation was published in 1817.
A History of the Jesuits; to which is prefixed a reply to Mr. Dallas's defence of that order by John Poynder (London: Baldwin, Cradock, and Joy, 1817).
Henry 'Orator' Hunt (1773-1835), William Cobbett (1763-1835) and Andrew James Cochrane-Johnstone (1767-1833). Hunt was imprisoned in 1800 for challenging to a duel his superior officer in the Marlborough yeomanry: there he encountered radical ideas for the first time, and soon began reading the works of William Cobbett. Hunt later invested in the Jacob's Well brewery in Clifton, just outside Bristol. Difficulties there required Hunt's residence in the city, and in 1807 he founded the Bristol Patriotic and Constitutional Association. He twice contested Bristol in elections, inciting the public in a way disconcerting to the establishment. In the wake of the poverty which struck Britain after the end of the Napoleonic wars (on which More commented frequently in her letters of this period), Hunt became involved with workers' movements, and was present at the Spa Fields Meetings of 1816 and 1817. He was delegated by the Hampden clubs at Bristol and Bath to petition members of parliament in the area in 1817. Though Cobbett had, early in the Napoleonic wars, held conservative views, he became an increasingly vocal critic of the Pitt administration and its pervasive use of sinecures and similar usually-accepted corruptions. In 1816, in the aftermath of the widespread social upheaval following the end of the wars, he established the Political Register, which Cobbett used to urge working people to campaign for parliamentary reform. The paper sold for tuppence, leading it to be jeered as 'two-penny trash' by its detractors. Its enormous popularity caused grave concern in government, and measures were passed by the Home Secretary, Lord Sidmouth, early in 1817 to limit its effects. Fearing arrest, Cobbett fled to America in May 1817. His friend Cochrane-Johnstone had been involved in a stock-exchange fraud, where in 1814 word had been spread in the south-east that Napoleon, and France, had been defeated. As shares soared, Cochrane-Johnstone benefited to the tune of nearly £5,000. He was tried and convicted of fraud in 1814.
The chapter to which More refers is entitled 'The Jesuits in England', p. 332. (Read at Google Books)
Mary Gisborne (b. 1789), daughter of Thomas Gisborne and Mary Babington Gisborne, had been engaged to John Bowdler the younger. He died in February 1815 from consumption before they could be married. In 1816 Bowdler's father, also John, published his son's Select Pieces in Prose and Verse, 2 vols (London: Cadell and Davies, and Hatchard, 1816). The fourth edition (1820), includes both portrait and journal. (Read at the Hathi Trust)
