The settlement of Sierra Leone in the 1800s was unique in that the population was composed of displaced Africans who were brought to the colony after the British abolition of the slave trade in 1807. Upon arrival in Sierra Leone, each "recaptive" was given a registration number, and information on their physical qualities would be entered into the Register of Liberated Africans. However, oftentimes the documentation would be overwhelmingly subjective and would result in inaccurate entries, making them difficult to track. In addition, differences between the Register of Liberated Africans of 1808 and the List of Captured Negroes of 1812 (which emulated the 1808 document) revealed some disparities in the entries of the recaptives, specifically in the names; many recaptives decided to change their given names to more anglicised versions which contributed to the difficulty in tracking them after they arrived in Sierra Leone.
