Oriana Souper was born in Bradfield, Berkshire, in circa 1874 as the oldest child of Fanny Emmeline and Francis Abraham Souper, a clergyman and headmaster of Bradfield College. The 1881 census listed her as six years old with three younger siblings, James F. T., Noel Beaumont, and Constance. At age twelve, her mother died, which left her to care for the household. Before her marriage, she worked as a matron at a prep school in Cheltenham.
Naturalist work
Reverend George Seaver described Wilson as "a good field naturalist and blest with a quick and lively observation", saying that she, like her husband, had a particular affinity for birds. Wilson collected the holotype for the Australasian bent-wing bat, for which Oldfield Thomas named the species Miniopterus orianae. In 1914, Leiper and Atkinson named a cestode genus after her, Oriana, with the type species of the genus as Oriana wilsoni. However, Oriana was recognised as a synonym of Tetrabothrius, so the species was renamed as T. wilsoni.
In 1897, she met Edward Adrian Wilson, at Caius House, Battersea, while he was conducting mission work in London. They married on 16 July 1901, three weeks before Edward left on the AntarcticDiscovery Expedition; the sledging flag she sewed for him was, after his death, displayed in Gloucester Cathedral and is now in the collection of the Scott Polar Research Institute. The wedding was in Hilton, Huntingdonshire, where her father was vicar. Wilson was widowed by her husband's death on the Terra Nova Expedition in March 1912. Fundraising efforts for families of those who died on the expedition were enormously successful, especially considering that only five men died. The Mansion House raised £75,000 in 1912,. As a widow, Wilson's income included £300 annually in a government pension ; £8,500 as a one-time payment from the Mansion House trust ; and a £636 salary from the British Antarctic Expedition. The loss of her husband was a blow to her faith, though she maintained it until the death of her brother during the Battle of the Somme. She did not remarry and had no issue. In New Zealand, she maintained a correspondence with poet Ursula Bethell.
In published works
In 2013, Katherine MacInnes published a book about Wilson entitled Love and Death and Mrs Bill: a play about Oriana, wife of Polar explorer Edward Wilson.
