John Watt jr. ('Jockey') was the younger son of James Watt of Greenock and the brother of James Watt. He trained as a book - keeper and started a trading enterprise, becoming a partner in the ship 'Fortune', with his father and others, and shipping goods between Glasgow and Bristol from 1760 - March 1762, when the ship was sold.
In April 1762 John Watt sailed to Virginia, North America. his father wrote that this was to gain more experience of trade. He drowned in October 1762 when his ship was wrecked in the Bahamas. There are some papers and a poem by James Watt of Greenock about the life of his son, at MS 3219/3/120.
After John Watt’s death, James Watt of Greenock dealt with any remaining accounts and annotated his son’s papers concerning the Fortune. James Watt, who was at that time living in Glasgow, helped with some of the outstanding business, the pursuit of debts from Matthew Watson, for example,and settled of a couple of debts as late as 1787.
A few papers from John Watt’s business affairs in Virginia were sent back to his father after John Watt’s death by Robert Cowan.
The papers accompanied the other family papers to Birmingham after the death of James Watt of Greenock. They were inherited by James Watt jr. after Watt’s death in 1819, but they do not appear on either of the inventories dated 1848 and 1873.
The papers of John Watt jr. were donated to Birmingham Reference Library as part of the ‘Muirhead papers’, in 1921 by Lionel B.C.L. Muirhead. The volumes were found in Muirhead Box I; most of the papers were found in Muirhead Box IV.
The ‘James Watt Papers’, purchased in 1994, did not hold any records concerning John Watt jr.
