It seems that you have missed the necessary options to answer this question, but anyway, the answer would be Olaudah Equiano and William Bradford. Olaudah Equiano was a prominent African in London, a freed slave who supported the British movement to end the slave trade and William Bradford who is from the West Riding of Yorkshire, who later moved to Leiden in Holland, and then in 1620 migrated to the Plymouth Colony on the Mayflower. Hope this answer helps.
