Timothy Discall (c.1747- ) and William Smith were found guilty on 25 July 1785 at Bodmin, Cornwall, of stealing iron graplings and other goods worth 23 shillings. Sentenced to 7 years transportation they were sent to the Dunkirk hulk, where they remained until they embarked for New South Wales on the Charlotte in March 1787. They were transferred to the Scarborough at Portsmouth on 6 April and arrived at Sydney in January 1788 as part of the First Fleet.
Discall was almost certainly the ordinary seaman Timothy Driscoll who was one of five former convicts who left the colony on the Kitty in June 1793.
