Puerto Rico, Records of Foreign Residents - FamilySearch Historical Records

Puerto Rico

What is in This Collection?
This collection of naturalization records for foreigners in Puerto Rico includes the years 1815-1845. This collection includes requests by foreigners for permission to reside in Puerto Rico (Letters of Domicile), some correspondence, lists of foreigners residing in Puerto Rico, and a few copies of final naturalization papers (Letters of Naturalization). During this time period, Puerto Rico belonged to Spain. Therefore, the documents pertain to foreigners becoming Spanish subjects and are written in Spanish. Puerto Rico was ceded to the United States in 1898. These records were transferred to the National Archives in 1943 and correspond to NARA publication T1170: Extranjeros (Foreigners) in Puerto Rico, 1815-1845. This collection is organized in alphabetical order by surname.

The Royal Decree of Graces of 1815 is a legal order approved by the Monarchy of Spain (King Ferdinand VII) in 1815, which contained the regulations for promoting the population, commerce, industry, and agriculture of the Island of Puerto Rico. Because of economic and political issues in Europe, many Spaniards and later Europeans took advantage of this grant, attracted also by the offer of free land to cultivate in the island. The new settlers were given a Letter of Domicile, which allowed them to reside and work legally in the island. After five years of residence in the island, they had a choice to make: become Spanish subjects and be granted a Letter of Naturalization that made them legal citizens, or reject the oath and return to their homelands. The majority of the settlers accepted the naturalization laws.

Naturalization is the process of granting citizenship privileges and responsibilities to foreign-born residents. These records were created to guarantee the rights of naturalized citizens to all the new settlers.

I Found the Person I Was Looking For, What Now?
Use naturalization records to:


 * Learn an immigrant’s place of origin
 * Confirm their date of arrival
 * Find records in his or her country of origin such as emigrations, port records, or ship’s manifests

You may also find these tips helpful:


 * Look for the Declaration of Intent (Letter of Domicile) soon after the immigrant arrived, and then look for the Naturalization Petition (Letter of Naturalization) five years later when the residency requirement would have been met. Look for naturalization records in federal courts and then in province, municipality, or city courts
 * An individual may have filed the first and final papers in different courts and sometimes in a different province if the person moved. Immigrants who were younger than 18 when they arrived did not need to file a Declaration of Intent as part of the process
 * If your ancestor had a common name, be sure to look at all the entries for that name before you decide which is correct
 * Continue to search the naturalization records to identify siblings, parents, and other relatives in the same or other generations who may have naturalized in the same area or nearby
 * The witnesses named on naturalization records may have been relatives of the immigrant. Search for their naturalization records

I Can't Find the Person I'm Looking For, What Now?

 * Check for variant spellings. Realize that the indexes may contain inaccuracies, such as altered spellings and misinterpretations
 * Try a different index if there is one for the years needed. You may also need to search the naturalization records year by year
