Mary-Harriet Southey (1784–1811): Daughter of Southey’s old Lisbon acquaintance, Richard Sealy (c. 1752–1821). She married Henry Herbert Southey in 1809.

Robert Southey, Senior (1745–1792): Southey’s father. A failed Bristol linen-draper, he was briefly imprisoned in 1792 ‘for a bill endorsed for a deceitful friend’. His release was secured by Elizabeth Tyler. He died in December 1792, after what his eldest son described as a ‘long’ decline.

Robert Castle Southey (1813–1828): Son of Tom and Sarah; born 14 December 1813, died 20 July 1828.

Sarah Southey (née Castle; 1782–1849): The daughter of a lawyer from Durham. She married Tom Southey in June 1810. Their nine surviving children were born between 1811–1824.

Thomas (‘Tom'; 1777–1838)Sailor and farmer. Southey’s younger brother and the one to whom he was in the 1790s closest. Tom entered the navy as a midshipman at the age of 12, saw action in several major battles of the French revolutionary wars (including Cape St Vincent and Copenhagen), was captured on one occasion, wounded on several others, and was made a lieutenant as reward for his bravery in the fight between Mars and L’Hercule on 21 April 1798.

Thomas Southey (1748–1811): Younger brother and at one time the business partner of Southey’s father, Robert Southey Senior. He was the beneficiary of the will of John Southey, to Southey’s envy and dismay, thus becoming a rich man. He spent his later years in Taunton, Somerset. Although unmarried, childless, and wealthy Thomas Southey was on distant terms with his brother Robert’s sons. Thomas Southey’s Will held no surprises — it cut his nephews off without a penny, ‘his last boast being ... that no one of his own name should ever be a shilling the better for him’.

John Spedding (1770–1851): Of Mirehouse, near Keswick. A boyhood friend of Wordsworth who became a close friend of the Southey family.

Percy Bysshe Shelley: (1792–1822): Eldest son of the wealthy Sussex landowner, baronet and MP, Sir Timothy Shelley (1753–1844). He became a published poet and novelist while still at Eton and was expelled from University College, Oxford, in March 1811 for writing The Necessity of Atheism (1811). In August 1811 he eloped with, and married, Harriet Westbrook (1795–1816), causing a temporary breakdown in relations with his family.

Samuel Simpson (1802–1881): An inveterate autograph hunter, Simpson wrote to Southey in 1821 and 1826, asking for Southey’s autograph. On both occasions Southey declined, sending Simpson humorous poems instead. Simpson’s identity is hard to be sure of, but he may have been the Samuel Simpson, born in Lancaster in 1802 and son of John Simpson (1779–1846), a retired West India merchant.

Harriet Shelley (née Westbrook; 1795–1816): Shelley’s first wife. They eloped and married in 1811. They had two children, but Shelley left her in 1814. She committed suicide two years later.
