Nearly 4 million enslavement records are now free to search on Ancestry

The collection documents enslaved people across 20 former British colonies between 1813 and 1840.

Ancestry has made nearly 4 million enslavement records searchable for free, giving descendants across the African diaspora another way to trace family connections and recover ancestors’ names. The release expands access to historical documents that can help families work through gaps left by slavery.

The company announced the collection Sept. 22, bringing together registers covering 20 former British colonies between 1813 and 1840. Users can explore the material with a free Ancestry account, the company said in its announcement.

The Former British Colonies Enslavement Registers were digitized from original manuscripts held by the United Kingdom’s National Archives. They include territories such as Jamaica, Barbados, Mauritius, Sri Lanka and the Cape of Good Hope.

Depending on the entry, researchers may find names, ages, family relationships, physical descriptions and places of origin. Some records identify an individual’s African origins before enslavement, while others document births, deaths, sales, escapes or release from slavery.

The registers were created after Britain abolished its transatlantic slave trade in 1807 to monitor enslaved populations and help prevent illegal trading. They recorded people within a system that treated them as property.

Today, those same entries can provide clues to family relationships that were otherwise difficult to establish.

Ancestry is working with University College London’s Centre for the Study of the Legacies of British Slavery, which is developing research on enslaved people in Jamaica.

Jamaican historian Suzanne Francis-Brown explains in an accompanying guide that some Jamaican registers identify mothers when they remained on the same property as their children. Later returns recorded changes, including births and the sale or death of individuals.

The colonial registers also have limits. Many people appear under only one name, paternal relationships may be missing, and some entries omit estate names. Francis-Brown recommends comparing the documents with baptism, marriage and burial records, alongside newspaper reports.

Researchers can begin searching the enslavement records with a name, approximate date or location. Those details may lead to additional entries that help connect an ancestor’s life under slavery with records created after emancipation.
