Cornelius Cain was tried 3 Aug 1789 at Surrey and received a sentence of 7 years transportation. He arrived in NSW aboard HMS Gorgon 1791. Cornelius arrived on Norfolk Island aboard the Pitt in Apr 1792.
1801: Cain Cornelius, Settler on Norfolk Island, convict pardon by King, yet in 1802 he was record as a convict under the name of Cornelius Kane.
Cornelius drowned 9 July 1803 at Norfolk Island. His death report in the Sydney Gazette 2 Oct 1803:
We are sorry to state, that a Boat returning from Phillip to Norfolk Island, with 38 large Hogs, was overset between Phillip and Nepean Isle by which unfortunate event the Cockswain (sic) and five men were drowned.
From the known causes of death, drowning is the most common, as the convict John Grant wrote in his journal in 1805:
Many poor men have lost their lives on boats between ships and the Isle of Norfolk, but no accident of this sort has taken place since my arrival. It is impossible for you to have any idea of the waves of the sea circulating around this place. Sometimes in a prefect calm the waves themselves make an imposing noise.
