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

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’.

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.

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.

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

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.

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

Mary Hannah Southey (b. 1812): Tom Southey’s second child. Born 12 November 1812.

Mary Southey (1750–1838): Southey’s paternal aunt, also referred to as ‘Aunt Maria’. Whereas Southey was on poor terms with his surviving paternal uncles, John and Thomas, he was on excellent terms with their sister. Mary Southey lived in Taunton, Somerset. After 1803 she provided important links between her nephew and his regional roots, and Southey stayed with her on his visits to the West Country. Mary, like her nephews, suffered from her two brothers’ lack of familial feeling.

Margaret Edith Southey (1802–1803): The first-born child of Robert and Edith Southey, who both doted on her. She died of hydrocephalus in August 1803.
