On 13 March 1804, Thomas Malthus married Harriet Eckersall, the eldest daughter of his first cousins John and Catherine Eckersall, who lived near Bath. Harriet became well-known at Haileybury College for hosting gatherings of notable scientists; eleven years younger than Thomas, she survived him by thirty years, remarrying after his death.[66]
The couple had a son, Henry, and two daughters, Emily and Lucille. Henry, the eldest, became vicar of Effingham, Surrey in 1835 and of Donnington, Sussex in 1837; he married Sofia Otter (1807–1889), daughter of Bishop William Otter and died in August 1882, aged 76. Emily, the middle child, died in 1885, outliving her parents and siblings. Lucille, the youngest, died unmarried and childless in 1825, at age 17.[56][67]
