One of the main goals for genealogists is finding marriage information about their ancestors.

Over the past few decades, thanks to volunteers, librarians, and archivists, a great number of indexes to marriage collections have been provided for free online. These searchable indexes provide specific marriage license, bond, and certificate information, and sometimes scanned images of the actual marriage documents 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 marriage information that is not included in the lists below. These different types can be found in 27 Ways to Find Ancestor Marriage Information.

The lists below are specific marriage indexes and record collections that are available for free online for the state of Illinois.

Note: Some links listed take you to a FamilySearch Collection of digital images. Near the bottom of the page, under Film/Digital Notes, is the name of each sub-collection. If there is a camera icon to the right of the name (in the Format column), then the collection’s 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. To take full advantage make sure that you are logged in to FamilySearch. The results may be different if you are signed in, rather than not.

Note: I have included links to Free Ancestry records and indexes. You do not need a subscription, but you do need an Ancestry account. You can view indexes without a subscription. If an image is associated with a record, in most cases, you will need a subscription, but the index does include very usable information.

Too much scrolling to get to pertinent posts. Please revert to “click to see more” under each heading. Thanks

Valid criticism. There are several ways, however, to access all articles. On the Home Page, there is a link to Recent Articles that display the title and link only. If you go to the Resources Menu Item and click on By Location, you can go directly to articles by state and resource category. And if you are interested in only one resource category for more than one state, just click on the resource category in the Resources Menu dropdown.
