Karl Hugo Hahn was a Baltic German missionary and linguist who worked in South Africa and South-West Africa for most of his life.

David Haliburton (1774-c.1833) of Muirhouselaw, Berwickshire, who in later life lived at Bushey Grove, Hertfordshire, was a distant cousin of Sir Walter Scott though his paternal grandmother. He served in the East India Company, as a member of the Board of Revenue and was responsible for exposing the corrupt practices of Edward and John Holland who both served as Governor of Madras. They used Avadhanum Paupiah to amass forged evidence against Haliburton which ended Haliburton's career in India. However, the scheme was uncovered by Lord Cornwallis, Governor-General of India, and Haliburton exonerated. Haliburton was a founder member of the Royal Asiatic Society. He never married and was the last of the line of Haliburtons written about by Walter Scott in his Memorials of The Haliburtons.
