SAINT HELENA: Between 1840 and 1867, some 27,000 enslaved Africans were liberated from ships in the Atlantic Ocean by the British Royal Navy and brought to the island of Saint Helena, where they eventually settled. There are few records concerning this population, particularly about where they were originally abducted from. New DNA sequencing of 19th-century human remains unearthed on the island indicates that many of these individuals were likely from an area between northern Angola and Gabon in Central Africa.
