Quick Summary

Genealogy company Ancestry has made nearly 4 million records documenting enslaved individuals in 20 former British colonies searchable online. These records, spanning from 1813 to 1840 and covering places like Jamaica and Barbados, were digitized with assistance from University College London’s Centre for the Study of the Legacies of British Slavery. The collection includes detailed personal information such as names, ages, physical descriptions, and family ties, originally intended by the British government to track enslaved populations post-abolition of the slave trade in 1807. Professional genealogist Nicka Sewell-Smith highlights how these records can now be used to trace family histories and restore human dignity to those previously treated as property.

Story summary

Nearly 4 million records documenting the lives of enslaved individuals across 20 former British colonies have been made searchable online for the first time, offering descendants a way to uncover their family histories. The genealogy company Ancestry partnered with the Centre for the Study of the Legacies of British Slavery at University College London to digitize and index this extensive collection. Spanning about 300,000 pages, these records cover enslaved people in locations like the Bahamas, Barbados, Jamaica, Mauritius, Trinidad, and South Africa's Cape of Good Hope between 1813 and 1840. Created after the abolition of the transatlantic slave trade in 1807, the registers aimed to prevent illegal trading and monitor the enslaved population with meticulous detail.
