Thomas Moore (1779–1852): Irish poet, playwright, and satirist, who in later life turned to writing biography, including a life of his friend Byron, whose Whig politics he shared. As a poet Moore achieved commercial success with his Poetical Works of the Late Thomas Little (1801); subsequent volumes included Irish Melodies (1808–1834), Intercepted Letters, or, The Twopenny Post-Bag (1813), and The Fudge Family in Paris (1818).

Edward Moor (1771–1848): Army officer and writer. He served in the army of the East India Company, rising to the rank of Major. After retiring back to his home county of Suffolk due to ill health, he produced the Hindu Pantheon (1810), which for over fifty years was the only authoritative book in English on the subject, and thus widely consulted. Other publications included Hindu Infanticide: an Account of the Measures Adopted for Suppressing the Practice (1811), Oriental Fragments (1834), and Suffolk Words and Phrases (1823).

James Montgomery (1771–1854): A radical journalist and poet. His father was a Moravian pastor and missionary and Montgomery was educated at the Moravian school at Fulneck, near Leeds. He was the editor of the Sheffield Iris newspaper from 1794 to 1825, and was twice imprisoned in the 1790s for publishing articles critical of the authorities. He authored The Wanderer of Switzerland (1807), a poem severely criticised in the Edinburgh Review (Southey sympathised).

Basil Montagu (1770–1851): Lawyer and author, illegitimate son of John Montagu, 4th Earl of Sandwich (1718–1792; DNB) and the actress Martha Ray (d. 1779; DNB). Montague, like Southey, was a member of Gray’s Inn, and was called to the Bar in 1798. He was a friend of William Wordsworth and Samuel Taylor Coleridge and in 1795 Wordsworth and his sister, Dorothy, undertook the upbringing of his two-year old son, Basil (1793–1830), by his first wife who had died in childbirth in 1793. His second marriage, in 1806, was to Laura Rush (d. 1806). Like his first wife, she died in childbirth.

Anna Dorothea Montagu (née Benson; 1773–1856): A former friend of Robert Burns, the widow of Thomas Skepper, a lawyer in York, and daughter of Edward Benson, a York wine merchant. She was Mary Barker’s friend, and married Basil Montagu in 1808.

John Mitford (1781–1859): Suffolk clergyman, who took little interest in his parochial duties but played an important role in London literary life. He was a noted editor (especially of the works of Thomas Gray), editor of the Gentlemans Magazine 1834–1850, and close friend of Samuel Rogers and Bernard Barton. In 1810 he wrote to Southey for advice about his poem, Agnes, the Indian Captive (1811).

George Mitford (1760–1842): Educated at Edinburgh University he practised briefly as a surgeon and in later life assumed the unauthorised title of ‘Doctor’. He married Mary Russell (1750–1830), a distant and wealthy relation of the Dukes of Bedford. Their only child was the writer Mary Russell Mitford (1787–1855; DNB). Mitford’s inverate gambling, social pretensions and extravagant expenditure brought his family close to ruin on several occasions. Southey wrote to Mitford in 1812 to acknowledge receipt of copies of works by Mary Russell Mitford.

Henry Hart Milman (1791–1868): Clergyman, poet and historian. His brilliant career at the University of Oxford included winning the Newdigate Prize in 1812 and he was elected Professor of Poetry 1821–1831. He became a Fellow of Brasenose College in 1814 and was ordained in 1816. Milman’s ecclesiastical career was equally illustrious, despite controversies over his orthodoxy prompted by his History of the Jews (1830), and he became a Canon of Westminster Abbey in 1835 and Dean of St Paul’s in 1849.

John Miller (1787–1858): Clergyman. Educated at the University of Oxford, where he won the Chancellor’s Medal for Latin prose and became a great friend of John Keble (1792–1866; DNB). In 1817 he delivered the University’s Bampton Lectures, on the subject of ‘The Divine Authority of Holy Scripture’. When he met Southey in 1820, Miller was a Fellow of Worcester College, Oxford, and Curate of Bishopstone, Wiltshire. He sent Southey a copy of his work, most probably his Bampton lectures.

Susannah Frances May (née Livius; 1767–1830): Wife of John May, whom she married in 1799.
