In April 2013, the northeastern section of Buenos Aires Province, particularly its capital, La Plata, experienced several flash floods that claimed the lives of at least 59 people. Alejandro Armendáriz, of the Radical Civic Union, was elected governor in 1983, when Raúl Alfonsín became president. Alfonsín lost the 1987 midterm elections, leading to the victory of Antonio Cafiero. From that year to 2015, all governors have been Peronists. The high population of the province makes it highly influential in the Argentine politics. With both ruling for two terms, the rivalry of president Carlos Menem and governor Eduardo Duhalde dominated the Argentine politics during the nineties. A similar case took place with president Cristina Fernández de Kirchner and governor Daniel Scioli. María Eugenia Vidal, from Republican Proposal, won the 2015 elections, and became the first female governor of the province.
Getting started with research in Buenos Aires
See FamilySearch Tutorials on Latin American Research.
Most of your genealogical research for Argentina will be in two main record types: civil registration and church records. This article will teach you methods for locating and searching these two record groups.
- Civil registration records are government records covering birth, marriage, and death. They are an excellent source of names, dates, places, and relationships.
- Civil authorities began registering births, marriages, and deaths in 1886. Even though the law was passed in 1886 most of the provinces started keeping records at different times. Most had the system going by 1900.
- Every municipal district was to make duplicate copies of their books. In Buenos Aires they kept the original books and send the copies to the Archivo General de Tribunales in the Federal District. In the provinces they were to be send the copies to the provincial or judicial archives of each province.
- According to the law, the public has liberal access to the civil records. The director of the civil archive is required to provide interested parties with a complete copy of any record, including marginal notes, under his jurisdiction.
- The Family History Library has not microfilmed the civil registration records of Argentina. The Library's collection continues to grow as new records are microfilmed and added to the collection from numerous sources. Don't give up if records are not available yet. The FamilySearch Catalog is updated periodically. Check it again every year for the records you need.
Locating Civil Registration Records
Civil registration records are kept at the local municipal district civil registration office (Dirección del Registro Civil). Therefore, you must determine the municipal district where your ancestor lived before you can find the records. The original book stays in the municipal office and duplicate copies are sent to the provincial or judicial archives of the province or the General Archive of the Tribunal in the federal district. Therefore, duplicates may also be available at the provincial level. If a letter to the town/city fails, write to the provincial office.
Your ancestor may have lived in a village that belonged civilly to a larger nearby town. In large cities, there may be many civil registration districts. You may need to use gazetteers and other geographic references to identify the place your ancestor lived and the civil registration office that served it. See Diccionario geográfico estadístico nacional argentino (1885). Although this gazetteer is in Spanish, the province is listed immediately after the name of the town.
Civil officials will generally answer correspondence in Spanish. Use the following address:
Dirección del Registro Civil
Oficina de Inscripciones y Rectificaciones
(postal code) (City), (Province), Argentina
Provincial Archives and Tribunal Archives
These archives maintain the duplicates sent to them by the municipal districts. You may write to these archives and request searches of the records. The public has access to these records. For the province of Buenos Aires, you will need to write to the following address:
Registro Provincial de las Personas
Calle 1 y 60
Buenos Aires 1900 CP
After deciding who has jurisdiction over the records for the time period you need, write a brief request to the proper office. Send the following:
- Full name and the sex of the person sought.
- Names of the parents, if known.
- Approximate date and place of the event.
- Your relationship to the person.
- Reason for the request (family history, medical, etc.).
- Request for a photocopy of the complete original record.
- Check or cash for the search fee (usually about $10.00).
Write your request in Spanish whenever possible. For writing your letter in Spanish, use the translated questions and phrases in this Spanish Letter-writing Guide.
The vast majority of Argentines were Catholic and were registered in the records of the local parish or diocese which are called registros parroquiales (parish registers). These records include entries for baptisms, marriage information, marriages, deaths, and burials. Often two and sometimes three generations are indicated in the records. In addition, church records may include church censuses, account books, confirmations, and other church-related records.
Church records are crucial for genealogical research, since civil authorities did not begin registering vital statistics until after 1886. After this date one should search in both church and civil records as there may be information in one that does not appear in the other. For instance the church records may only list the godparents whereas the civil records may list the grandparents.

- The Spanish Documents Script Tutorial also provides lessons and examples.
Tips for finding your ancestor in the records
Effective use of church records includes the following strategies.
- Search for the relative or ancestor you selected. When you find his birth record, search for the births of his brothers and sisters.
- Next, search for the marriage of his parents. The marriage record will have information that will often help you find the birth records of the parents.
- You can estimate the ages of the parents and determine a birth year to search for their birth records.
- Then repeat the process for both the father and the mother.
- If earlier generations (parents, grandparents, etc.) do not appear in the records, search neighboring parishes.
- Search the death registers for all known family members.
