IGI Batch Numbers for Illinois, USA

Click on the batch number of interest and enter the surname you are searching for to be taken to the relevant search results at familysearch.org

Some towns/counties are listed in the IGI under more than one state/province. Where batch numbers for a town/county with the same name have been found in a different state/province as well as this one, that state/province appears in the "Other States/Provinces" column as a clickable link (or more than one if appropriate). Clicking this link will take you to the relevant entry on that state/province's page (which may be either for the same town or for another town elsewhere with the same name).

If you see a ** beside a batch number, this batch either covers more than one location or includes entries with different names/spellings for what may be the same Town, Parish, Church or Chapel. Common such discrepancies are to find both St. and Saint or to have both hyphenated and unhyphenated versions of the same name. Sometimes the same town will be listed with a different county even in the same batch. It should be remembered that much of the indexing performed by the LDS was done by people (who were all volunteers, I believe) who were not familiar with the local geography. Clicking on the ** will display a list of alternative locations for that batch.

If dates are available for a batch number they will be shown to the right of the batch number. These dates are taken from the detail page of the first entry in the batch. They may overlap or be consecutive and may have errors and are provided only as a guide to what might be available in the batch in question.
