One of the main goals for genealogists is finding birth, marriage, and death (BMD) information about their ancestors.
Over the past few decades, thanks to volunteers, librarians and archivists (as well as the largest of them all – FamilySearch), a great number of indexes to birth, marriage, and death collections have been provided for free online. These searchable indexes provide specific BMD information, and sometimes scanned images of the actual birth, marriage, and death certificates themselves. These free online collections have hundreds of millions of records in them in total.
There are a great number of online and offline collections that may include birth, marriage, and death information that are not included in the lists below. For example, newspapers, draft registration files, naturalization records, etc. have BMD info. To find out which types of other records may include BMD information, please see:
- 27 Ways to Find Ancestor Birth Information
- 22 Ways to Find Ancestors Marriage Information
- 21 Ways to Find Ancestors Death Information
The lists below are specific birth, marriage, and death indexes and record collections that are available for free online for the state of Colorado.
Note 1: Many of the links listed below take you to a FamilySearch Collection of digital images. In many cases there is a link to the digital collection in the middle of the page, but also near the bottom of the page under Film/Digital Notes is the name of each sub-collection. If there is a camera icon at the right of the name (in the Format column) then the collections’ images are browsable. If there is a camera with a key icon, it is only available at a Family History Center or affiliated library. If there is a film reel icon, then it is only available in microfilm format, not digital. Please also note that I have listed below only BMD databases that are accessible digitally from your computer (or tablet/phone)
Note 2: I have included links to Free Ancestry records and indexes. You do not need a subscription, but do need an Ancestry account. Without a subscription you can view indexes. If there is an image associated with a record, in most cases you will need a subscription, but the index does include very usable information.
