Free Genealogy Research Guide

Practical, source-by-source guide to researching your family history for free, using U.S. public records, archives, and the best free online indexes.

1. Start with What You Know

Write down every name, date, and place you already know in your direct line. Interview the oldest living relatives first — their memory of names, dates, and ports of entry is the cheapest research tool you have. Save photos and documents to a single cloud folder before they get lost.

Interview the oldest relatives first and record everything — names they heard as children, the town nobody can spell anymore, which church held the funerals. Documents can wait; memories can't. Every professional genealogist's regret list starts with a grandmother's story they didn't write down, because one remembered maiden name routinely saves months of record work.

2. Vital Records (Birth, Marriage, Death)

Civil registration of births and deaths is generally a 20th-century phenomenon. Order modern certificates from your state vital-records office — see vital records by state. For older events, look to church registers, family Bibles, and county courthouse marriage registers.

Tip: A death certificate is the single most useful genealogy document — it usually lists parents’ names, spouse, last residence, occupation, and place of burial.

The privacy clock is your friend: states seal recent vital records but open them with age — birth records typically after 75 to 125 years, deaths sooner, and the indexes often sooner still. That's why your great-grandmother's 1912 birth certificate is orderable while your cousin's is not. For births that were never registered — common for home births into the 1930s — look for delayed registration files, created decades later with affidavits from relatives that are themselves genealogical gold.

3. Federal Census (1790–1950)

The U.S. census is the workhorse of American genealogy. Each release adds new questions: 1850 added every household member’s name, 1880 added relationship to head of household, 1900 added month and year of birth, 1930 added home value. The most recent open census is 1950.

Free indexes:

The census follows a 72-year privacy rule: 1950 opened in April 2022, and 1960 arrives in 2032. Going backward, know the one great gap — the 1890 census was almost entirely destroyed after a 1921 fire, so bridge that decade with state censuses, city directories, and voter rolls. Every surviving schedule from 1790 to 1950 is free at the National Archives and mirrored on the major genealogy sites.

4. Immigration & Naturalization

Ellis Island (1892–1957) records are free at libertyellisfoundation.org; Castle Garden (1820–1892) records at FamilySearch (Castle Garden collection). Naturalization papers are filed in the federal or county court that handled the case — check the SearchSystems court records directory by state. NARA holds a free naturalization records guide.

Passenger manifests get richer the later they are — a 1907 arrival lists the relative left behind and the relative being joined, with addresses on both sides of the ocean. Naturalization after 1906 is federal and standardized (petitions, declarations, certificates), and those files routinely contain the exact birth village that family legend had reduced to "somewhere near Kiev."

5. Military Records

Service records, pension files, and draft cards are gold for connecting generations. Highlights:

Draft cards are the great equalizer: nearly every American man born between roughly 1873 and 1900 filled out a World War I card, and the World War II "old man's registration" caught those born 1877-1897 — signatures, addresses, employers, next of kin, all free. Service files themselves burned in large numbers for the Army (the 1973 St. Louis fire), so pension files and draft cards often carry the story the personnel file lost.

6. Land & Probate

Land patents, deeds, and wills tie families to places. The Bureau of Land Management hosts a free land-patent search covering 5+ million federal land grants. State land records (the 13 colonies plus Hawaii, Texas, Kentucky, Tennessee, and parts of Vermont and Maine) are at state archives. For wills, the county Surrogate Court / Register of Wills holds probate files.

Federal land patents at the BLM's General Land Office site are free, searchable by name, and cover the public-land states — homesteads, cash sales, military bounty land. Probate files are the other underused gem: a will names the family exactly as the deceased understood it, including the daughter in another state and the son written out, with the court file preserving fights the family history politely forgot.

7. Cemetery & Obituary Indexes

Free volunteer-built sites cover almost every U.S. cemetery:

Volunteer-built grave indexes now cover a staggering share of American burials, photos included — and the photo of the stone often carries what the index missed: a maiden name, a lodge emblem, a spouse on the same monument. Cross-check against the death index rather than trusting either alone; stones and certificates disagree more often than you'd think, and the certificate isn't always the one that's right.

8. Best Free Online Genealogy Sites

  1. FamilySearch — run by The Church of Jesus Christ of Latter-day Saints, free, 9 billion+ names indexed
  2. U.S. National Archives
  3. USGenWeb — volunteer-run, county-by-county
  4. Cyndi’s List — 350,000 categorized free links
  5. WikiTree — collaborative single family tree, free
  6. Your local public library — Ancestry Library Edition is usually free on library computers

Build the free stack before paying for anything: FamilySearch for records and trees at no cost, the National Archives catalog for originals, Chronicling America at the Library of Congress for millions of free searchable newspaper pages — where the obituaries, marriage announcements, and scandals live. Paid sites add convenience and some exclusive collections; they do not add the government records themselves, which belong to everyone.

9. DNA Testing

Autosomal DNA tests (AncestryDNA, 23andMe, FamilyTreeDNA, MyHeritage) find cousins out to about the 4th–5th generation. Y-DNA traces the direct paternal line (men only); mtDNA traces the direct maternal line. Upload raw data for free to GEDmatch for cross-database matching.

DNA results are not private — matches are visible to other testers. Read the privacy policy before testing.

Use DNA for the matches, not the ethnicity pie chart — the chart is an estimate that shifts with every algorithm update, while a shared-DNA match to a documented second cousin is evidence that survives every update. The technique that breaks brick walls is clustering: group your matches by which of them match each other, and the clusters sort themselves into your four grandparent lines.

10. Archives & Libraries

Most state archives publish free indexes online: see the National Archives directory of state archives. The Library of Congress catalog includes city directories, county histories, and family histories. The FamilySearch Library in Salt Lake City and its local FamilySearch Centers offer free access to billions of records.

State archives hold what the internet hasn't gotten to: original registers, court books, institutional records, and the local knowledge of archivists who've watched researchers chase the same families for decades. Email before visiting — most archives will check an index for free and tell you exactly what to order, and many county historical societies will photograph a record for the cost of postage.
