John Blacket or Blackett

???? - 1832


'John Blacket' was shown in an unknown capacity with John Mann against the Grand Ance estate in Grenada and again with John Mann as the owners of the enslaved people upon Belvedere in Grenada, both in 1817. It seems highly likely that this was John Blackett merchant of London, who was instrumental in the transportation of convicts to Australia: his first contract in 1819 was for the convict ship named Grenada, and in 1809 he is known to have sent a vessel to Grenada. The wills of both John Blackett and his son of the same name were proved in 1832.

  1. John Blackett and John Mann were among ten defendants in a suit brought by Lucy Campbell in 1807, ‘Bill and Complaint of Lucy Campbell', C 13/2108/27, TNA; they were characterised by Nicholas Crawford as creditors of her husband James Campbell of Invera and Argyle estate on Tobago. John Blackett was also a party with Lucy Campbell and others to the sale of Tivoli, St John and Rose Hill plantations in Grenada to Samuel Marryat in 1821.

  2. In 1812 John Blackett and John Mann were parties to a conveyance by Henry Page of slave-property in Grenada, St Vincent, Antigua and Trinidad.
