Freedom of Information Day: The Genealogist’s Secret Weapon You’re Not Using Enough

Freedom of Information Day: Every March 16th, we mark Freedom of Information Day — James Madison’s birthday — and most genealogists let it pass without firing off a single FOIA request. That’s a missed opportunity. Here’s how to change that.

Madison was born on March 16, 1751, and we honor his legacy of open government by celebrating public access to federal records. The Freedom of Information Act became law in 1966, giving every American the right to request records from federal agencies. For genealogists, that’s not a civics footnote — it’s a research superpower.

FOIA is dramatically underused in our community. People flock to Ancestry, dig through FamilySearch, and order vital records from county clerks — all great moves. But when it comes to federal records about deceased relatives? Most researchers leave a mountain of material untouched. Let’s fix that.

FOIA is So Vital for Genealogy Research

FOIA applies to living individuals and, critically, to deceased ones. Many genealogically valuable records are held by federal agencies that won’t show up in your usual database searches. We’re talking about military files, immigration documents, and federal agency records that can fill in decades of missing family history.

Here’s the framework: you submit a written request to the specific federal agency holding the records, provide enough identifying information, and wait. Yes, there’s waiting. But what comes back can be extraordinary.

Military Records: Service Files, Pension Records, and Draft Registrations

Where to request: The National Archives and Records Administration (NARA) handles most military service records through its National Personnel Records Center (NPRC) in St. Louis. Submit requests at archives.gov/veterans using Standard Form 180 (SF-180).

What you need: Full name, branch of service, approximate service dates, and date/place of birth. Social Security number helps if you have it.

Practical tips:

• The 1973 NPRC fire destroyed millions of Army and Air Force records from 1912–1964. Don’t give up — alternate sources like morning reports, enlistment records, and unit records may survive.
• Pension files for Civil War veterans are genealogical gold. Request these through NARA’s online catalog or by mailing to the National Archives in Washington, D.C.
• WWI and WWII draft registration cards are largely digitized on FamilySearch, but original files sometimes contain additional pages. A direct NARA request can surface material the scans missed.

Immigration Records: Naturalization Files, Visa Applications, and Passenger Manifests

Where to request: U.S. Citizenship and Immigration Services (USCIS) holds naturalization records and visa files created after 1906. Submit a USCIS Genealogy Program request at uscis.gov/genealogy — this is a separate pathway from standard FOIA and is specifically designed for genealogical requests.

For passenger manifests and older immigration case files, NARA holds records predating USCIS jurisdiction.

What you need: Full name (including maiden name and all known aliases), country of origin, approximate arrival date, and date of birth.

Practical tips:

• The USCIS Genealogy Program indexes are searchable before you pay. Search first, then order the full file. A naturalization file can include the original declaration of intent, petition for naturalization, photographs, and detailed biographical data.
• For relatives who went through Ellis Island, the manifest is just the start. The full immigrant case file — if one exists — can be dramatically more detailed.
• Don’t overlook visa applications for relatives who immigrated after 1924. These files, held at NARA, often include photographs and detailed personal histories.

Federal Agency Records: FBI Files and Beyond

This is where it gets genuinely surprising. The FBI maintained files on an enormous range of individuals — union members, political activists, people who applied for federal employment, and many ordinary citizens caught up in investigations they may never have known about.

Where to request: Submit directly to the FBI via its FOIA/Privacy Act portal at vault.fbi.gov. The FBI’s “Vault” already has thousands of declassified files online — search there first.

What you need: Full name, date of birth, date of death (deceased status often speeds processing), and any known aliases or organizational affiliations.

Practical tips:

• For deceased individuals, explicitly state the date of death in your request. Privacy protections are reduced for deceased persons, and agencies process these requests differently.
• Other agencies worth querying: the Office of Personnel Management (federal employment records), the Department of State (passport applications going back to the 1800s), and the Bureau of Indian Affairs (if you’re researching Native American ancestry).
• Be specific. Vague requests get vague results or rejections. Identify the specific record type you believe exists and why.

One More Thing: Use NARA’s Online Tools First

Before you submit any request, search the National Archives catalog at catalog.archives.gov. Millions of records are already digitized and free. FOIA is for what isn’t online yet — and there’s plenty of that.

Freedom of Information Day is the perfect annual reminder to think bigger about your federal record sources. Madison gave us the principle. Congress gave us the law. Now use it.

The AI assisted in generating an early draft of the content, but every paragraph was subsequently reviewed, edited, and refined by me.
