James Douglas Blackett (1828-1912) and his brother William Richard Blackett (1830/31-1902) were both stock jobbers and members of The London Stock Exchange. (After the Stock Exchange’s “Big Bang” in 1986 jobbers became known as “market makers”.) Born in Wapping, London, they were two of the sons of John Anderson Blackett, a former publican born in the village of North Sunderland, close to the north-east coast of Northumberland, and were grandsons of James Blackett, a Trinity House agent born in neighbouring Bamburgh. This line of Bamburgh Blacketts can be traced back to James Blackett, baptised in Bamburgh in 1693, the son of John Blackett, baptised in Berwick-upon-Tweed in 1663, and grandson of Nicholas Blackett.
