Pitcairn-Norfolk in Pitcairn Islands

Pitkern, also known as Pitcairn-Norfolk or Pitcairnese, is a language spoken on Pitcairn and Norfolk islands. It is a mixture of English and Tahitian, and has been given many classifications by scholars, including cant, patois, and Atlantic Creole. 

Following the Mutiny on the HMS Bounty on 28 April 1789, the British mutineers stopped at Tahiti and took 18 Polynesians, mostly women, to remote Pitcairn Island and settled there. A pidgin was formed based on English and Tahitian so that the English mutineers could communicate with the Tahitian women they brought to the previously uninhabited Pitcairn Island. The Pitkern language was influenced by the diverse English dialects and accents of the crew.
