The Enchantress arrived in Port Jackson from Mauritius on 16th January 1834 with one male prisoner.
John Knockton was born in County Galway. He was 34 years of age and had been a soldier Officer's servant and groom. He was convicted of Mutiny at Port Louis Mauritius on 20 October 1833.
He held a ticket of leave for the district of Liverpool which was cancelled in 1850 for being absent from his district.
He was granted a conditional pardon in 1852.
It may have been this same John Knockton who was employed as a "lunatic keeper" at the Parramatta Invalid Establishment in 1853 and who was a witness at the trial of George Watkins. (Empire 8 February 1853)
