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.

Margaret Southey (b. 1811): Eldest child of Tom Southey and his wife Sarah. Born 7 March 1811.

Margaret Southey (1752–1802): Southey’s mother. Born Margaret Hill, she married Robert Southey Senior in 1772. The marriage produced nine children, of whom five died young. She was dominated by her older half-sister, Elizabeth Tyler, with whom Southey spent a great deal of his childhood. After the bankruptcy and death of her husband in 1792, Margaret moved to Bath, running a boarding house in Westgate Buildings. Her continued financial difficulties — possibly exacerbated by the extravagance of her half-sister — caused Southey great anxiety.

Louisa Southey (née Gonne; d. 1830): Daughter of Southey’s old Lisbon friends, the Gonnes, and second wife of Henry Herbert Southey. They married on 21 August 1815. Louisa died giving birth to their tenth child.

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.
