Title: Charles Darwin
Content:  house-hunting in London, bouts of illness continued and Emma wrote urging him to get some rest, almost prophetically remarking "So don't be ill any more my dear Charley till I can be with you to nurse you." He found what they called "Macaw Cottage" (because of its gaudy interiors) in Gower Street, then moved his "museum" in over Christmas. On 24 January 1839, Darwin was elected a Fellow of the Royal Society (FRS). On 29 January, Darwin and Emma Wedgwood were married at Maer in an Anglican ceremony arranged to suit the Unitarians, then immediately caught the train to London and their new home.
Title: Down House
Content:  The Darwin family in 1841 was finding their London house increasingly cramped: both Charles and his wife Emma preferred living in the countryside, as they were disturbed by the constant noise and severe coal smoke air pollution of central London, and they had two young children, William (b. 1839) and Anne (b. 1841). Darwin approached his father Robert Darwin for financing, and with the caution that he should try living in an area for some time before being committed to a move, was given approval to start house hunting. Charles and Emma sought somewhere about 20 mi from London with railway access, 
Title: 1842 in science
Content: September 14–17 – English naturalist Charles Darwin and his family settle at Down House in Kent. 
Title: Down House
Content:  Down House is the former home of the English naturalist Charles Darwin and his family. It was in this house and garden that Darwin worked on his theory of evolution by natural selection, which he had conceived in London before moving to Down. The Grade I listed building stands in Luxted Road, 1/4 mi south of Downe, a village 14+1/4 mi south-east of London's Charing Cross. The village was still known as Down when Darwin moved there in 1842. In his day, Downe was a parish in Kent, but it subsequently came under Bromley Rural District. Since 1965, it has lain within the London Borough of Bromley. The house, garden and grounds are in the guardianship of English Heritage. They have been restored and are open to the public.
Title: Publication of Darwin's theory
Content:  Darwin's attention turned from pigeons to seedlings, experimenting with subjecting plants to conditions which might produce variation. His family helped with this and with tracking bees, experimenting (unsuccessfully) to try to find out what would influence their flight path. His wife Emma Darwin was now known throughout the parish for helping in the way a parson's wife might be expected to, and as well as providing nursing care for her own family's frequent illnesses, she gave out bread tokens to the hungry and "small pensions for the old, dainties for the ailing, and medical comforts and simple medicine" based on Robert Darwin's old prescription book. Charles Darwin also took on local duties, increasing his social standing by becoming a Justice of the Peace and a magistrate. To accommodate the needs of his large family and accommodate visiting cousins further house extensions got under way. In November 1857 he escaped the worries for a week's recuperation at Lane's Moor Park spa.
Title: Charles Galton Darwin
Content:  will have smaller families and will hand on that instinct to their children. In the long run society will consist mainly of people with the strongest instinct to reproduce. This would ultimately have dysgenic effects. In later years he travelled widely, an enthusiastic collaborator across national borders and an able communicator of scientific ideas. He died at Newnham Grange in Cambridge (the house where he was born) on New Year's Eve 1962/3; he was cremated at Cambridge Crematorium on 4 January 1963. He and his late wife are commemorated with a memorial at St Botolph's Church, Cambridge; she was cremated, the funeral was in Wimbledon, where she had been living.
Title: St Mary's Church, Downe
Content:  The Church, as with the village of Downe itself, is closely linked with the naturalist Charles Darwin who lived at nearby Down House from 1842 to his death in 1882. John Brodie Innes was the vicar from 1846. Darwin played a leading part in the parish work of the church, but from around 1849 would go for a walk on Sundays while his family attended church. Charles's wife, Emma Darwin, was Unitarian and the family would face away when the Anglican Trinitarian Creed was read. Several members of the Darwin family are buried in the churchyard, Charles's brother Erasmus Alvey Darwin (died 1881), Emma Darwin (1896), Charles and Emma's children Mary Eleanor Darwin (1842), Charlie (1858), Elizabeth (1926), Henrietta (1927); Elinor Monsell (1954) and her husband, Charles and Emma's grandson Bernard Darwin (1961). Charles Darwin had wished to be buried here too but was instead buried in Westminster Abbey. Emma Darwin's sister Elizabeth Wedgwood and Charles and Emma's Aunt Sarah Wedgwood are also buried together in the St Mary the Virgin churchyard.
Title: Darwin–Wedgwood family
Content: Marianne Darwin (1798 – 18 July 1858), married Henry Parker (1788–1858) in 1824. ; Caroline Sarah Darwin (1800–1888), married Josiah Wedgwood (grandson of the first Josiah Wedgwood) ; Susan Elizabeth Darwin (1803–1866) ; Erasmus Alvey Darwin (1804–1881) ; Charles Robert Darwin (1809–1882) (see below) ; Emily Catherine Darwin (1810–1866), was Charles Langton's second wife. The son of Erasmus Darwin, Robert Darwin was a noted physician from Shrewsbury, whose own income as a physician, together with astute investment of his inherited wealth, enabled him to fund his son Charles Darwin's place on the Voyage of the Beagle and then gave him the private income needed to support Charles' chosen vocation in natural history that led to the inception of Darwin's theory of evolution. He married Susannah Wedgwood, daughter of Josiah Wedgwood (see above), and they had the following children. 
Title: Charles Darwin's education
Content:  On 31 October Charles returned to Cambridge for the Michaelmas Term, and was allocated a set of rooms on the south side of First Court in Christ's College. Although several biographers since the 1980s have referred to these rooms as traditionally having been occupied by the theologian William Paley, research by John van Wyhe found that historical documentation did not support this idea. Darwin now had breakfast every day with his older cousin William Darwin Fox. This was Fox's last term before his BA exam, and he now had to cram desperately to make up for lost time. At the

Content:  the train home to Shrewsbury, then on the 28th travelled to Maer Hall. On 29 January 1839, Charles married Emma at Maer, Staffordshire in an Anglican ceremony arranged to also suit the Unitarians, conducted by the vicar, their cousin John Allen Wedgwood. Emma's bedridden mother slept through the service, sparing Emma "the pain of parting". Immediately afterwards Charles and Emma rushed off to the railway station, raising their relative's eyebrows, and ate their sandwiches and toasted their future from a "bottle of water" on the train. Back at Macaw Cottage, Charles noted in his journal "Married at Maer & returned to London 30 years old", and in his "E" notebook recorded uncle John Wedgwood's views on turnips. See the development of Darwin's theory for the ensuing developments, in the context of his life, work and outside influences at the time.
