| Registro Central de Esclavos, 1872 |
Have You Researched Your Puerto Rican Enslaved Persons?
Many genealogists are unaware that enslaved people in Puerto Rico can be traced by name using Spanish colonial records created in the years leading up to abolition. To begin this research, it is essential to understand three interconnected record sets, created at different stages of the abolition process.
Three Key Record Sets for Researching Enslaved People in Puerto Rico
1. Cédulas de esclavos- Individual identity documents
- Issued before the abolition-era enumeration
- Often include physical descriptions, ownership, residence, and sometimes parentage
- Local enumeration of enslaved people
- Conducted primarily circa 1871–1872, with earlier local enumerations (including 1867)
- Organized by jurisdiction, plantation, or household
- Centralized compilation of enumeration data
- Used for emancipation administration and compensation
- Captures enslaved people at the edge of freedom
The Registro Central de Esclavos (1872)
For genealogists researching enslaved ancestors in Puerto Rico, the Registro Central de Esclavos (Central Registry of Slaves), created in 1872, is one of the most important, and most overlooked, record sets documenting slavery on the island just before slavery was abolition.
This registry was compiled one year before slavery was abolished in Puerto Rico, making it a rare snapshot of enslaved individuals, their owners, and family relationships at the very edge of freedom.
When Did Slavery End in Puerto Rico?Slavery in Puerto Rico officially ended on March 22, 1873, when the Spanish Cortes passed the Abolition of Slavery Act for Puerto Rico.
However, emancipation was conditional:
- Formerly enslaved people were required to work for their former enslavers for three additional years
- Or purchase their freedom through a state-regulated compensation system
- The system functioned more like indentured labor than true freedom
Important clarification:
The Moret Law (1870) did not abolish slavery outright. Instead, it granted limited freedom to:
- Children born to enslaved mothers after 1868
- Enslaved people over age 60
- Enslaved people who served the Spanish state
True, unconditional emancipation, without forced labor or compensation, came only after these transitional requirements expired.
Why the 1872 Registry MattersThe Registro Central de Esclavos was created as part of Spain’s effort to inventory enslaved people before emancipation. It was used primarily to manage compensation claims by slaveholders.
For genealogists, this registry is invaluable because it may include:
- Full name of the enslaved individual
- Town or municipality
- Place of birth (often Africa, the Caribbean, or Puerto Rico)
- Name of the enslaver
- Legal status
- Age, sex, and physical description
- Family relationships (parents, spouses, children)
- Notations made as emancipation approached
In many cases, this may be the only surviving document that names an enslaved ancestor before freedom.
Locating These RecordsRecords of the Spanish Colonial Government of Puerto Rico, including the Registro Central de Esclavos (1872), are preserved as part of:
- Puerto Rico (Territory under Spanish occupation, 1509-1898
- Office of the Governor of Puerto Rico
These records are held by the National Archives and Records Administration and are also accessible in part through FamilySearch.org, Puerto Rico Slave Registers, 1859–1880
Although Puerto Rico became a U.S. territory in 1898, Spanish-era records remained intact and were later incorporated into U.S. archival custody.
Note: These records are not fully digitized. Many are poorly indexed
The 1872 registry page shown above demonstrates the bureaucratic language of slavery:
- Individuals are listed as property, yet paradoxically described in deeply human terms:
- family, origin, and physical traits
- Columns reflect ownership and legal control rather than personhood
- Marginal notes may reveal changes in status as emancipation approached
Prior to the creation of the 1872 Registro Central de Esclavos (centralizaed registry), Spanish colonial authorities conducted a general enumeration of enslaved people known as the Empadronamiento General de Esclavos. This census-like record documented enslaved individuals by jurisdiction, plantation, and household. It often lists family relationships and physical descriptions.
Some surviving examples date to 1867, while others reflect the 1871–1872 enumeration phase immediately preceding abolition.
These census-like records often document enslaved individuals by:
- Jurisdiction
- Plantation or household
- Family relationships
- Physical descriptions
The New York Public Library collected Spanish colonial records as part of its global legal, colonial, and abolition-era documentation efforts, especially in the late 19th and early 20th centuries.
This mirrors the record collections of:
- Cuban slavery records in Boston
- Brazilian manumission records in Paris
- Haitian colonial records in Spain and France
Digitized examples of the Empadronamiento General de Esclavos (1867) are preserved in the NYPL collections and can provide critical pre-abolition context, particularly when used alongside the 1872 registry.
Puerto Rican descendants may also want to scour the NYPL Digital Collections, including holdings at the Schomburg Center for Research in Black Culture, for registered slave records.
Case Example: Empadronamiento / Cédula Record
Slave Registry: Lucía, described as mulata and creciendo (still growing), was enslaved by Teodosio González, a resident of Utuado, Barrio de Caguana, Arecibo. Although her father is not named, her mother was Juana de Frecia.
This type of individual record, whether a cédula or local empadronamiento entry, provides the personal detail that later feeds into the centralized 1872 registry.

These records work together.
- Cédulas tell us who someone was
- The 1872 Registro Central de Esclavos tells us where they stood when slavery ended
5 Research Pro Tips
Researching enslaved ancestors in Puerto Rico is complex but possible.
If you are researching Afro-Puerto Rican or enslaved ancestors:
- Search pre-1873 church records alongside the registry
- Track enslavers forward into 1873–1880 labor contracts
- Look for surname adoption patterns after emancipation
- Pair registry entries with Spanish civil records and municipal censuses
- Do not assume freedom in 1873 meant independence; many families remained tied to former owners for years
This research reminds us that emancipation was not a single date, but a long, contested process.
