The children of Robert Cottle, an unsuccessful Bristol tailor and draper. The family included Amos, Joseph and Robert (?1780–1858), a painter and founder of his own religious sect (‘the Cottlelites’), and five sisters, Elizabeth (c. 1764–1789), Mary (?1772–1839), Ann (?1780–1855), Sarah (d. 1834) and Martha (c. 1785–1800). Southey seems to have been acquainted with the entire Cottle family. After their secret marriage in November 1795, his wife Edith lived with the Cottle sisters for some of the time Southey was absent in Spain and Portugal.
