Free Colorado genealogy records
Where to find free birth, death, marriage, census, probate, land and newspaper records for Colorado, and which offices hold what. Last checked Oct 2026.
Check before relying on these:
- Start of statewide registration: CDC lists state-office births from 1910 and deaths from 1900; a published chart gives 1907 for both. Use county records to fill the gap.
Birth, death and marriage records
When statewide registration began: The state office has deaths from 1900 and births from 1910 (some counties earlier). Statewide registration is usually dated to 1907.
- Births: the state office has them from 1910, and some counties from earlier.
- Deaths: the state office has them from 1900.
- Marriages: kept by the county clerk and recorder.
Current office addresses, fees and eligibility rules are on the CDC "Where to Write for Vital Records" page for Colorado. Records that are too recent are usually restricted to close family. Older ones are often free to view as indexes or images on the free databases below.
Before statewide registration, some counties and larger cities kept their own registers. Church baptism and burial registers, family Bibles, obituaries and cemetery records fill the gaps.
Census records
- Federal censuses from 1790 to 1950 are free to search on several sites. The 1950 census is free from the National Archives' 1950 Census site, and NARA's census research pages explain each year.
- Almost all of the 1890 federal census was destroyed after a 1921 fire, so families can "disappear" between 1880 and 1900.
- Colorado took a federally assisted state census in 1885.
- Census records only exist for years after statehood or territorial organization.
Probate and land records
- Probate: District courts handle probate (Denver has its own Probate Court). Deeds are at the county clerk and recorder. Older probate files are often transferred to the state archives.
- First land transfers: Colorado is a federal public-land state. The original federal land patents (homesteads, cash sales, military warrants) are free to search on the BLM General Land Office Records site. Homestead case files themselves are at the National Archives.
- Later deeds: once land was in private hands, every sale was recorded locally by the county.
Historic newspapers
- Chronicling America: Colorado newspapers is the Library of Congress's free archive of digitized historic newspapers, filtered to this state.
- History Colorado is Colorado's partner in the National Digital Newspaper Program, which digitizes the state's papers for Chronicling America.
- Colorado Historic Newspapers Collection: a free state digital newspaper site.
- Obituaries are the best newspaper find for genealogy. If your family's paper isn't digitized, the local public library or historical society may have it on microfilm.
Archives, libraries and societies
- Colorado State Archives: the state's official archives, with older government records such as court, land, military and often vital records.
- History Colorado: historical society or research library with manuscripts, photographs and local histories.
Tips for the local level
- Find which county your ancestor's town was in at the time. County lines moved as new counties were created, and records stay with the county that created them.
- Call or email before visiting. Many courthouses have moved older books to the state archives or a county records center.
- Look for the local genealogical society and the county page of the free, volunteer-run USGenWeb Project, which often have transcriptions and cemetery lists.
Big free (and freemium) databases
- FamilySearch Research Wiki: Colorado: a free, volunteer-edited guide to Colorado record types, useful for double-checking anything on this page.
- FamilySearch: a free nonprofit genealogy site with indexed records and digitized microfilm. You need a free account to search.
- Find a Grave: free, volunteer-built cemetery listings, often with headstone photos.
- BillionGraves: free headstone photos tagged with GPS locations.
- National Archives genealogy pages: guides to federal census, military, immigration and land records.
- Ancestry: a large subscription site. Some indexes are free with a free account, and many public libraries offer free in-library access.
