How to Research Your Family History for Free

Television ads make genealogy look like something you buy: pay a monthly subscription, watch leaves sprout on a tree. In reality, an enormous share of American genealogical records — every federal census through 1950, millions of vital records, passenger lists, military files, and church registers — can be searched completely free. The paid sites are convenient, but they are not required, and even their databases can usually be reached free through a public library. This guide walks through how to research your family history for free, in the order experienced genealogists actually work: from what you already know, backward one generation at a time.

1. Start with What You Already Know

The cardinal rule of genealogy is to work from the known to the unknown. Before touching any database, write down everything you can about yourself, your parents, and your grandparents: full names (including women's maiden names), and the dates and places of births, marriages, and deaths — even approximate ones. Every fact you record now is a search term later.

Then raid the house. "Home sources" are the documents families accumulate without thinking of them as records: birth and marriage certificates, obituary clippings, funeral cards, military discharge papers, family Bibles with handwritten registers, naturalization certificates, old letters, photo albums with names penciled on the back, yearbooks, and address books. Finally, interview your oldest relatives — soon, and ideally with a recorder running. Ask open-ended questions ("What do you remember about your grandmother?") rather than quizzing for dates. Family stories are often garbled in the details but right in the outline, and they point you toward the counties and decades where the records will be.

2. Build Your Tree on FamilySearch.org (Free)

FamilySearch.org is the largest free genealogy site in the world, operated by the nonprofit FamilySearch International (sponsored by the Church of Jesus Christ of Latter-day Saints, though the site is for everyone and pushes no religious content at researchers). A free account gets you billions of indexed records — censuses, vital records, church registers, probate files, and microfilmed records from around the world — plus a collaborative shared family tree and the FamilySearch Research Wiki, an encyclopedia of what records exist for every U.S. county and most countries, and where to find them.

One caveat on the shared tree: because anyone can edit it, treat other users' entries as clues rather than facts, and attach actual record images as sources for your own entries. A few record collections are viewable only at a FamilySearch center or affiliate library due to contracts — there are thousands of these centers, free to visit, and the catalog tells you when a trip is needed.

3. Work Backward Through the Free U.S. Censuses

The federal census is the backbone of American genealogy. Taken every ten years since 1790, it is released to the public after 72 years, so everything through the 1950 census is open — and every released census is searchable free. FamilySearch has them all; the National Archives also hosts the 1950 census with its own search at 1950census.archives.gov.

Find your family in 1950, then step back to 1940, 1930, and so on. From 1850 onward the census names every person in the household with age, birthplace, and occupation; 1880 and later give each person's relationship to the head of household and their parents' birthplaces — which is how you leap back a generation. The 1900 census even records each mother's number of children born and still living, and immigrants' year of arrival. Two warnings: almost the entire 1890 census burned, so expect a 20-year gap between 1880 and 1900, and spellings are wildly inconsistent — search phonetic variants and try a wife's or child's distinctive first name when a surname search fails.

4. Confirm Dates with State Vital-Records Indexes

Censuses give you approximate ages; birth, marriage, and death records give you exact dates, parents' names, and maiden names. Many states have posted free searchable indexes to their older vital records — examples include the Ohio death index, the Missouri Secretary of State's digitized death certificates (1910–present minus 50 years, with free images), the Illinois statewide marriage and death indexes, and West Virginia's free vital-records images. FamilySearch also hosts free vital-records indexes for most states, and the FamilySearch Research Wiki page for your state lists exactly what exists, for which years, and where.

Remember that statewide registration is younger than people expect — most states began between 1880 and 1920 — so for earlier events look to county courthouses, church registers, and newspapers. Marriage records are the outlier: counties recorded marriages from their founding, making them often the earliest vital record available. Obituaries and death notices in old newspapers fill many gaps; see our guide to free historical newspaper archives for where to search without a subscription. And a burial place is itself evidence — our guide on finding where someone is buried shows how to use graves and cemetery records in your research.

5. Trace Immigrants Through NARA Records

For most American families there is an immigration story, and the National Archives and Records Administration (archives.gov) holds the two key record groups. Passenger arrival lists survive for major ports — substantially complete from 1820 onward — and from 1892 the Ellis Island-era manifests grew rich with detail: last residence, nearest relative in the old country, who paid the passage, and the name and address of the relative they were joining in America. New York arrivals from 1820–1957 can be searched free at the Statue of Liberty–Ellis Island Foundation's passenger database, and FamilySearch indexes the other ports.

Naturalization records are the other half of the story. Before 1906 an immigrant could naturalize in any court, so look in the county courts where the family lived; after September 1906 the process was standardized and duplicate copies went to the federal government. Post-1906 petitions and declarations of intention are genealogical gold — birth date and town, arrival ship and date, spouse and children — and are held by NARA and, for later files, by USCIS through its Genealogy Program. City directories can pin down exactly where an immigrant family lived each year between censuses, which tells you which court and which parish to search; our guide to old city directories explains how to use them.

6. Use Library Editions of the Paid Databases

Here is the secret that saves genealogists hundreds of dollars a year: the big subscription databases sell institutional versions to libraries, and your library card is the key. Ancestry Library Edition offers nearly everything in a personal Ancestry subscription and is available free inside thousands of public libraries. HeritageQuest Online (censuses, Revolutionary War pension files, county histories, the Freedman's Bank records) is offered by many library systems with remote access from home using your card number. Many libraries also license MyHeritage Library Edition, Fold3 (military records), and Newspapers.com Library Edition. Check the "research databases" or "genealogy" page on your library's website — and if your local system is small, note that some state libraries offer these databases to any resident of the state who registers for a card.

7. Understand What DNA Testing Can and Can't Do

DNA testing is the one genuinely non-free tool in modern genealogy, so understand what you're buying before you spend. A test is superb at two things: confirming or disproving suspected relationships, and connecting you with living cousins who may hold records and photos you don't. It will not hand you a family tree — DNA matches only become ancestors when you and your matches compare well-researched paper trails. Be skeptical of ethnicity percentage estimates, which are statistical inferences that shift as reference panels change and are least reliable at the sub-continental level. Also weigh the privacy questions honestly: your results implicate biological relatives who never consented to testing, and testing can surface unexpected parentage. If you do test, tests frequently drop to $39–$59 in holiday sales, and free third-party tools like GEDmatch let you compare across companies — there is no need to pay full price or test with every company.

8. Organize as You Go

The most common beginner mistake isn't a wrong record — it's finding the right record and losing track of where it came from. Adopt three habits from the start. First, cite every source, even informally: "1930 census, Cook County, Illinois, ED 16-202, sheet 4B" is enough to find it again. Second, keep a research log — a simple spreadsheet of what you searched, where, and what you found (including negative results, which save you from repeating dead-end searches). Third, use consistent file names for downloaded images, such as surname_firstname_year_recordtype. Free software options include RootsMagic Essentials and Gramps (open source), or simply build your tree on FamilySearch and keep your log in a spreadsheet. Whatever you use, record where every fact came from — future you will be grateful.

9. Let a Local Historical Society Break Your Brick Walls

Eventually every researcher hits a "brick wall": an ancestor who appears from nowhere, a family that vanishes between censuses. The single most underused free resource at that point is the local historical or genealogical society in the county where your family lived. Societies hold what never got digitized: church registers, cemetery transcriptions, funeral home ledgers, school and tax records, surname files built up over decades, and county histories with biographical sketches. Just as valuable, their volunteers know the local quirks — that the county line moved in 1873, that the courthouse fire spared the deed books, that the German congregation's records went to a synod archive two states away. Many societies answer mail-in research questions for free or a small donation. Find the society for your ancestor's county in our directory of historical societies by state.

A Realistic Free Research Plan

• Week 1: Record what the family knows, gather home documents, interview the oldest relatives.
• Week 2: Create a free FamilySearch account and enter yourself, parents, and grandparents with sources.
• Weeks 3–4: Trace each grandparent back through the 1950, 1940, and 1930 censuses; confirm dates in vital-records indexes.
• Month 2: Visit the library for Ancestry Library Edition; pursue passenger lists and naturalizations for immigrant lines.
• Month 3: Write to the historical society in each ancestral county about your hardest problem.

Frequently Asked Questions

Is there a completely free version of Ancestry?

FamilySearch.org is the closest thing — a genuinely free site with billions of records and a collaborative tree. And Ancestry itself is free to use inside most public libraries as Ancestry Library Edition, so you can search its databases without a personal subscription.

How far back can I trace my family for free?

Most Americans can reach the early-to-mid 1800s using free censuses, vital records, and county records alone, and lines connected to well-documented colonial families can go much further. The limit is usually record survival, not money — the further back you go, the more the work shifts from typing names into search boxes to reading original county and church records.

What is the best free genealogy website?

FamilySearch.org, without much competition: it is free, nonprofit, and holds billions of searchable records plus the Research Wiki. Strong free supplements include the National Archives (archives.gov), Chronicling America for newspapers, Find a Grave for burials, and county USGenWeb volunteer sites.

Do I need a DNA test to research my family history?

No. DNA is optional — a tool for confirming relationships and finding living cousins, not a substitute for records research. Most family trees are built entirely from paper records, and a DNA match only becomes meaningful when both parties have documented trees to compare.
