How to Research Your Family History in Missouri

Missouri hands researchers one of the great free resources in American genealogy: the Missouri State Archives has digitized the state’s death certificates – 1910 onward, released on a rolling fifty-year schedule – and serves the images free online, alongside a suite of free databases covering naturalizations, military service from the War of 1812 through the World Wars, and more. Around that hub sit a French colonial record older than the Louisiana Purchase, a city-county split that divides St. Louis research in two, and the German river towns whose parish books reach back to their founding.

Start With Vital Records

Statewide registration began in 1910 under what is now the Bureau of Vital Records; an earlier county-level attempt (1883–1893) left surviving register fragments in many counties that are worth checking for 1880s births and deaths. The flagship is the free Missouri Death Certificates database at the State Archives – certificate images, name-searchable, from 1910 forward as each year passes the fifty-year mark. For deaths, Missouri research starts there, full stop. Births are restricted; use the death certificates, censuses, and church books to reconstruct earlier generations.

Marriages are county records from each county’s founding, recorded by the Recorder of Deeds; long runs are microfilmed, digitized, and indexed statewide. Divorces are Circuit Court files.

The County: Recorder And Circuit Court

Missouri’s 114 counties (plus one special case below) formed from 1812 territorial beginnings; chart parent counties, and expect the familiar scatter of 19th-century courthouse fires, with the Archives’ microfilm as the rescue.

  • Recorder of Deeds – deeds and mortgages from county formation, and the marriage books.
  • Circuit Clerk / Probate Division – court files and probate: wills, administrations, inventories, guardianships. Older probate files across the state are heavily microfilmed through the Archives’ local-records program, and many counties’ files are digitized.
  • County and township tax books add the annual trail.

The St. Louis Split

In 1876 the City of St. Louis separated from St. Louis County – permanently. Since then they are two jurisdictions with two complete sets of offices: city Recorder and courts for city events, county offices in Clayton for county events. Before 1876, records are in the city’s custody. Every St. Louis-area search must begin by asking: city or county, and before or after 1876?

The Missouri State Archives

The Archives in Jefferson City (a Secretary of State office) is among the most digitization-forward in the nation. Beyond the death certificates: the Soldiers’ Records database (War of 1812 through WWI service cards – Missouri’s Civil War records cover both Union and Confederate service, fitting a state that fought itself), a statewide naturalization index, Supreme Court case files, county and probate microfilm through the Local Records Preservation Program, and the Missouri Digital Heritage portal aggregating collections from institutions statewide. The State Historical Society of Missouri (Columbia, with research centers in St. Louis, Kansas City, and beyond) adds newspapers – a superb statewide run – manuscripts, and county histories.

The French And Spanish Deep End

Missouri’s record trail predates the Purchase. Ste. Genevieve (founded circa 1750) and St. Louis (1764) kept Catholic sacramental registers from their earliest years, recording French, French-Canadian, Native, and enslaved residents by name; published translations and diocesan archives make them accessible. Spanish-era land grants – confirmed and litigated after 1804 – generated claim files with settlement testimony, held between the Archives, the federal land records, and published abstracts. Fur-trade families connect through St. Louis’s notarial-style records and on to Québec’s indexed parishes.

German Missouri And Other Paths

The Missouri Rhineland – Hermann, Washington, Westphalia, and the river counties – was settled in the 1830s–1850s by German emigrants whose Lutheran and Catholic parish registers name home villages and often outrun the civil record; regional and diocesan archives hold the books, and the home parishes are increasingly digitized. Ozarks families reward tax-list and land-patent work plus the deep county-history literature.

African American ancestry: Missouri was a slave state; enslaved ancestors appear in the enslaving families’ probate inventories, deeds, and tax books, with the circuit courts’ freedom suits – St. Louis’s are famous and digitized – documenting hundreds who sued for liberty. Add the Freedmen’s Bureau’s Missouri/Arkansas district records, post-1865 marriage books, and Black church and school records; Kansas City and St. Louis Great Migration families run through directories, parishes, and the SHSMO collections.

Online And Free

The death certificates, Soldiers’ Records, and naturalization index are free. Missouri Digital Heritage is free. FamilySearch carries digitized county marriage, probate, and deed runs plus diocesan registers. BLM’s General Land Office site documents the federal patents beneath most farms. Newspapers and censuses sit with SHSMO and the platforms, free through Missouri libraries.

Research Checklist

  1. Start every line at the free death-certificate database; work backward from the informant’s answers.
  2. Check the 1883–1893 county register fragments for late-1800s events.
  3. Work the Recorder (marriages, deeds) and the probate files via the Archives’ microfilm program.
  4. St. Louis family? Resolve city vs. county and pre- vs. post-1876 before searching.
  5. French-era line: Ste. Genevieve and St. Louis parish registers, then the Spanish land claims.
  6. German river-town line: parish register → named home village → digitized German books.
