Transcribe Spanish Genealogy Records

Spanish-language records are among the longest continuous runs in genealogy. The Council of Trent required parishes to keep baptism and marriage registers from the 1560s, and Catholic parishes across Spain and Latin America kept them for centuries after. Spain's civil registry began in 1871, and the countries of Latin America introduced their own at different dates. The result is a great deal of surviving paper, written in hands and spellings that change from one century to the next.

KleioBase reads those records and translates them into English. That is step one. What it builds next is the point: every person, date and place connected into one family archive.

How KleioBase reads Spanish records

You upload a scan or a photo of the record. KleioBase reads the handwriting and gives you a transcription in the original Spanish alongside an English translation. It then pulls out what a genealogist needs: names, dates, places, relationships, and the people who stood as godparents or witnesses.

Spanish records often carry more than one event in a single entry. A burial entry may record the death, the sacraments received, where the body was laid, and who was named to carry out the will. KleioBase keeps those as separate facts on the right people rather than flattening them into one line.

What we tested before writing this page

We ran real Spanish-language scans through the same extraction every upload uses. An early seventeenth-century baptism from a Seville parish book came back with the child, both parents, the godfather and the priest. A 1719 burial entry from a village in Guadalajara came back with the deceased, her husband, the executors she named and the other people on the page, ten in all. A 1922 civil marriage from Buenos Aires in our own test archive came back with both spouses and their families. That is a handful of documents, not an accuracy figure, and we are not claiming one.

One limit we saw. The Seville page holds six entries, and a normal scan read the first of them. On the other crowded register pages we tested, a deep scan, which uses a stronger model and more credits, read far more of the page. If a page holds many entries and you need all of them, use deep scan or upload a crop of the entry you want.

From a scan to a connected profile

Reading the record is step one of four:

1. Upload the scan or photo.
2. Process it - KleioBase reads and translates the record and pulls out the people and events.
3. Review the result and fix anything the AI misread. Faded ink and surnames spelled three ways are where Spanish records get tricky, and the review step is where you stay in control.
4. Confirm it - KleioBase creates or updates person profiles and links the record to them.

Once confirmed, the ancestor who appears in a baptism, a marriage and a burial becomes one profile with every document attached. As the archive grows, KleioBase suggests likely duplicate people to merge and points out gaps where a generation is not yet documented.

Why Spanish records are hard, and how the review step helps

Older entries spell by ear, so the same word can appear with a b or a v, with or without an h. Dates and ages are written out in words. People carry two surnames, a paternal and a maternal one, and a clerk may record both, one, or a different one in the next document. That is exactly where two records of one person can look like two different people.

KleioBase gives you a first reading you can work from and then hands you the controls. You confirm what is right and correct what is not, and nothing enters your archive until you do.
