If you have roots in the western side of Puerto Rico, chances are you’ve hit a wall trying to find records from the early 1800s. FamilySearch has a lot, but not everything. And some of the best records are sitting in places most people never think to look.
This week, someone in the Facebook group Sociedad Puertorriqueña de Genealogía shared something I hadn’t seen before: the Archivo Digital de Aguadilla. Free, online, and full of parish records going back to 1780. I want to walk you through what it is and how to use it, especially if you’re just getting started.
What Is the Archivo Digital de Aguadilla?
The Archivo Digital de Aguadilla is a free online archive of historical documents from Aguadilla, Puerto Rico. It was created by Haydée E. Reichard, and the heart of the collection is the Libros Parroquiales (Parish Books) from 1780 to 1843: baptism, marriage, and burial records from the parishes of Aguada and San Carlos Borromeo.
These are the kinds of records that can take you back generations before civil registration began in 1885. If your family is from the western part of the island, this archive is worth knowing.
The records have been alphabetized by surname, which makes it much easier to navigate than flipping through unindexed handwritten pages.
Browsing the Site
When you land on the site, you’ll notice it’s primarily in Spanish. Don’t let that stop you. Tools like Google Translate can help you read the navigation and any descriptions.
The site is organized into categories you can explore from the footer or sidebar:
- Libros Parroquiales: Parish birth, marriage, and death records (this is the main collection)
- Genealogía: Genealogical collections
- Documentos Nuevos: Newly added documents
- Ensayos: Historical essays
- Other collections from researchers like Herman Reichard, Ramón Añeses, and Jaime González
Click the hamburger menu (the three lines, ≡) in the top right corner to access all sections, including Noticias, which is where they announce new additions to the archive.
How to Search
Here’s where it gets a little different from what you might be used to on FamilySearch or Ancestry. There are two ways to search, and the one that looks most obvious is actually the less useful one.
Option 1: Site-Wide Keyword Search
Go to “Buscar en Archivo Digital” in the main menu, type a surname, and click Buscar. This searches across all posts and pages on the site.
Option 2: External Archive Database (Better for Parish Records)
On that same search page, look for a link that says “BUSQUEDA”. Click it. This takes you to an external tool at archivonacional.com where the full Haydée Reichard collection is searchable as a proper database. This is the better option for finding a specific person.
Using the Parish Book Viewer
When you open one of the parish book entries, an embedded document viewer loads right on the page. It looks like this:

Inside the viewer, the records are sorted alphabetically by surname. You have a few options for navigating:
- Use the Índice (Index) button to pull up a list of surnames and jump directly to the one you’re looking for.
- Use “Otros Libros” (Other Books) to switch between the available volumes: baptisms, marriages, and death records across different years.
My Experience: The Search That Didn’t Work
I want to save you some frustration. When I first tried the site, I searched for “Acevedo” using the viewer’s built-in search bar. It came back with no results at all.

I almost moved on. But I tried the Índice instead (again, click the hamburger menu ≡), and there it was: a long list of Acevedos.

The lesson: do not expect this search to work like FamilySearch or Ancestry.
- Use the Índice.
- Browse by letter.
The site was built differently, and once you understand that, it makes much more sense.
What You’ll Find Once You Get There
Once you locate a record, you’ll be reading handwritten text from the 1700s and 1800s. That’s both exciting and a little intimidating if you’ve never done it before.

There are no typed summaries or extracted data fields. You’re reading the original handwriting directly. A few things to keep in mind:
- If you’re comfortable reading cursive in English, you can figure out many of the letters.
- AI tools can help you get started with a transcription, but always verify what any AI produces by comparing it word-by-word to the original image. AI makes mistakes with old and new handwriting!
- If you want to build your skills, the Spanish Paleography Digital Teaching and Learning Tool is a wonderful free resource designed to help people read early modern Spanish handwriting from the sixteenth and seventeenth centuries.
A Few Honest Limitations
This archive is a labor of love, not a commercial database. That means:
- The collection is not exhaustive. Some years and volumes are missing because access to the originals was limited.
- The site is primarily in Spanish.
- The search tool inside the viewer does not behave like a modern search engine. Use the Índice.
For related Puerto Rico records, the Enlaces page on the site links to the broader Archivo Digital Nacional de Puerto Rico at adnpr.net, which is worth bookmarking.
One More Resource Worth Knowing
The same Facebook group also shared another resource this week: Rutgers University’s Digital Library of Historians of Puerto Rico.
This is a digital collection of books by Puerto Rican historians, including Francisco Moscoso, Fernando Picó, David Stark, and Francisco Scarcano.
If you’re not fluent in Spanish, having these books in digital form means you can use Google Translate to read them or use them as a reason to start learning Spanish. Context matters in genealogy, and these historians can help you understand what life was like for your ancestors.
Start Looking
If your family is from Aguadilla or the surrounding area, or if you simply want to push further back than civil records allow, give the Archivo Digital de Aguadilla a try. Go to the site, click on a book, and look through the index. You might be surprised what comes up.
And if you find something, share it with the community. That’s how we all move forward.
