Illinois Genealogy Records with Birth Information

Recording births by county officials did not start until 1877 in Illinois and 1916 by state authorities. Yet there are many records which have birth information into the 1700's.

The following chart lists those records, with the approximate years of birth covered by those records. (See explanation below the chart)

Records that have birth information
* How the birth years covered were determined for each type of record"
 * This chart is in order by the earliest birth years covered for each type of record. The birth years were determined by:
 * 1) The date each record type began
 * 2) An estimated age of about 70 years for the oldest persons included in the record type.
 * Obviously, there were a few who were older, while most were much younger than 70.
 * Death records, for example, started in 1877. A 70-year-old person who died in 1877 would have been born about 1807.
 * Marriages, on the other hand, were more often for people between 16-30 years of age.
