George Warren was a Methodist missionary who went to Sierra Leone in 1811.
Rev. Warren had been an itinerant preacher travelling through England and Wales for John Wesley's circuits. Warren volunteered to become a missionary and educationalist in Sierra Leone, and sailed there in 1811 on board the Traveller, captained by Paul Cuffee. He was accompanied by three school teachers: Jonathan Raynor, John Healey and Thomas Hirst.
He was a juror during the trial of Samuel Samo in 1812.
