When was the  Anglo-Irish physician, naturalist and collector died who's niece recovered from spinal deformity due to Sarah "Crazy Sally" Mapp?
Sally Mapp Sarah "Crazy Sally" Mapp (died 1737) was an English lay bonesetter, who gained fame both by performing impressive bone-setting acts in Epsom and London, and by being a woman in a male-dominated profession. Bone-setting was a medical practice used to manipulate and fix musculoskeletal injuries using manual force. Mapp grew up in Wiltshire, England, and learned about the practice from her father, who was also a bone-setter. She frequently fixed horse racing injuries, but her most famous case was fixing the spinal deformity of Sir Hans Sloane's niece.
Maria Kinnaird Maria Kinnaird (1810–1891), born on St. Vincent, was orphaned by a volcanic eruption and was later adopted by the politician Richard Sharp, known as "Conversation Sharp". Sharp was once considered possibly to be the most popular man in London of his time. Through her adoptive father, she inherited not only a considerable fortune but a wide network of influential friends and contacts, particularly among Whig circles. She became a prominent socialite and leading hostess in London during the mid-Victorian period and was described as being an "accomplished, attractive, and intelligent woman". In 1835, she married Thomas Drummond, who developed the use of Drummond Light in surveying. She would be her husband's mainstay during his final years as Under-Secretary for Ireland (1835–1840).
