Daniel Stuart (1766–1846): Newspaper proprietor and journalist. Originally a printer, he bought the Morning Post in 1795 and turned it into the leading anti-government newspaper and a very profitable venture. Though he sold the Morning Post in 1803, he retained an interest in the Courier, which he acquired in 1800–1801, though it is disputed how much influence he had over the newspaper’s contents. Stuart employed Southey to write poems for the Morning Post at a guinea a week in 1798–1799, and again in 1801–1803.

Charles Swan (b. 1797–?1838): Writer and clergyman, whose works included Gesta Romanorum; or Entertaining Moral Stories (1824). From Morton, near Gainsborough, Lincolnshire, he attended Catherine Hall, Cambridge, matriculating in 1817. He was ordained as a deacon in 1820 and, in 1824, took up the post of Chaplain on HMS Cambrian. He published an account of his experiences as Journal of a Voyage Up the Mediterranean, Principally Among the Islands of the Archipelago and In Asia Minor, Including Many Interesting Particulars Relative to the Greek Revolution.

James Tate (1771–1843): Schoolmaster, clergyman, and classicist. Educated at the Grammar School in Richmond, Yorkshire, and Sidney Sussex College, Cambridge. In 1796 he became headmaster of Richmond School and transformed it into an educational powerhouse. He rejected corporal punishment and instead attempted to enthuse pupils with his own love of learning. He published textbooks on the classics and also Horatius Restitutus (1832), which attempted to arrange the works of Horace in chronological order. Politically he was a Whig and a proponent of Catholic Emancipation.

George Taylor (1772–1851): Gentleman farmer, classicist and occasional contributor to the Quarterly Review. Taylor lived in County Durham and became acquainted with Southey through the latter’s brother, Tom. His son, Henry Taylor, later became a close friend of Southey’s and his literary executor.

Charles Benjamin Tayler (1797–1875): Clergyman and writer for the young. Southey wrote to him in 1820 in connection with some poems Tayler had sent him.

Isabel Southey (1812–1826): Southey’s youngest daughter.

John Cannon Southey (1743–1806): The eldest brother of Southey’s father, who lived at Taunton, Somerset. His work as a lawyer led to him accumulating a substantial fortune of £100,000. Although he was unmarried, he refused to help either Robert Southey Senior, thus ensuring the latter’s imprisonment for debt in 1792, or his nephews, to whom he left nothing in his Will. Southey visited his uncle in 1802, describing his miserly existence to John May. In 1806, he recorded that his uncle ‘had thanked God upon his death bed that he had cut me off’.

Katharine (‘Kate’) Southey (1810–1864): Sixth child of Robert and Edith Southey. She did not marry and in her later years lived at Lairthwaite Cottage in Keswick with her aunt, Mary Lovell.
