Puerto Rico Slavery Records

Slavery Registry of 1872
In 1872, the Spanish government ordered a central registry of all slaves living in Puerto Rico at that time. This data is available at FamilySearch (images only) and Ancestry.com (index only). This record type is fairly unique for Latin America as it was created the year before the slaves were freed by the government in 1873. The records helped the government pay the owners for each freed slave. Even so, slavery continued in spots for several more years.
