My ancestor appears in a civil record but I cannot find a military record. Is that normal?

Yes. Most Puerto Rican men who served in the colonial militia were not career soldiers, and records survival is uneven. Begin with what you know — the civil record — and use it to build a search profile: name, approximate birth year, municipality, and family members' names. Then check the filiación indexes at the Archivo General Militar de Segovia and local militia records at the Archivo General de Puerto Rico.

What language are these records in?

All colonial military records are in Spanish, written in 18th- and 19th-century administrative script. The vocabulary is specialized but consistent: the same fields (naturaleza, pelo, ojos, estatura) appear in nearly every filiación. This course explains each field and what it means for your research, even if you do not read Spanish fluently.

Are Spanish colonial military records available online?

Very few are fully digitized. PARES (the Portal de Archivos Españoles) has partial digitization of some Archivo Histórico Nacional collections, but the bulk of Puerto Rico colonial military records held at the Archivo General Militar de Segovia require a direct research request by email or mail. Module 4 walks through the request process step by step.

Could my Puerto Rican ancestor appear in military records even if they were of African descent?

Yes. Enslaved people were not enrolled in the official militia rolls. However, the Milicias de Pardos y Morenos — separate units for free men of African descent — are well-documented and genealogically rich. If your ancestor was a free person of color, they may appear in Pardo Militia filiaciones or muster rolls. Each module of this course notes where Pardo Militia records differ from regular militia records and how to find them.

How do military records connect to church and civil records?

Military records and church records overlap significantly. A filiación records an ancestor's municipality of birth and parents' names — exactly the information you need to anchor a search in baptism registers. Module 5 shows how to build a research strategy that uses filiaciones to confirm and extend what you find in civil and church sources.

My ancestor lived in a rural municipality far from San Juan. Would they have a military record?

Possibly. The provincial militia extended to most of Puerto Rico's towns, not just San Juan. By the late 18th century, virtually every municipality had its own militia company. Rural militiamen were enrolled in filiaciones and muster rolls just as San Juan garrison soldiers were. The records may be harder to locate, but they exist.

Spanish Colonial Military Records

A five-module intermediate course on tracing Puerto Rican ancestors in Spanish colonial military records: filiaciones, muster rolls, repository access, and GPS-compliant research strategies.

Intermediate

Who Is This Course For?

This course is for intermediate researchers who want to use Spanish colonial military records to document Puerto Rican ancestors from the colonial period (1508-1898).

You may be:

A researcher who has exhausted civil and church records for an ancestor born before 1885 (when civil registration began) and needs an alternative source of biographical data
Someone researching a family line of free African descent who needs sources beyond baptismal and marriage registers
A researcher who suspects a male ancestor served in the colonial militia and wants to know how to find and interpret those records

Prerequisite knowledge: This course assumes you can navigate FamilySearch’s Puerto Rico Civil Registration and Catholic Church Records collections, and that you understand how Puerto Rican double surnames work. If you need that foundation, start with Navigating Civil Records first.

Language note: You do not need to be fluent in Spanish to use this course. Military records use standardized vocabulary that this course translates and explains field by field. Reading handwritten originals is helpful but not required to begin your research.

Why Military Records Matter for Puerto Rican Genealogy

Spanish colonial military records are among the most genealogically detailed documents produced in Puerto Rico before civil registration began in 1885. A single filiación (enlistment record) can provide:

The soldier’s full name and any alias
His age and birthplace (naturaleza), recorded as his municipality
His parents’ full names
His wife’s name and the names of any children, when noted
His physical description: height, eye color, hair color, and complexion
His occupation before military service
The date and place of enlistment

For a researcher working in 18th- or early 19th-century Puerto Rico, where baptismal and marriage records are the primary biographical sources, a filiación can unlock a generation or more of ancestry that would otherwise be inaccessible.

A Note on Records Survival

Not every Puerto Rican man who served in the colonial militia left a surviving record. Fire, humidity, administrative disorganization, and the disruption of the Spanish-American War (1898) all took their toll. The bulk of surviving Puerto Rico colonial military records are held in Spain — at the Archivo General Militar de Segovia — not on the island. This means that accessing these records requires either a trip to Segovia or a research request sent by email or mail.

The good news: Segovia’s staff is accustomed to receiving genealogical research requests and responds reliably, though turnaround time can range from weeks to several months. Module 4 provides a step-by-step request guide.

Course Standards

All research strategies in this course follow the Genealogical Proof Standard (GPS) developed by the Board for Certification of Genealogists. Evidence is classified using the Three-Layer Framework: source type (original, derivative, or authored), information quality (primary, secondary, or indeterminate), and evidence value (direct, indirect, or negative).

If you are new to GPS, the Research Standards: GPS guide provides a full introduction.
