Places to Discover Your Illinois Ancestors

by Jennifer Holik | Jan 15, 2013

The history of Illinois is varied. The French first controlled it in 1678; the English had it beginning in 1763. The state of Virginia controlled it from 1778 until 1784, when the U.S. Federal government gained control. Finally in 1818, the land was created in the state we know today. For those with Illinois ancestors, the places to research online and in person are many. These resources provide not only genealogical data, but also historical data and social history. It is important to include all these aspects when researching your family's history.


Illinois State Archives

The Illinois State Archives is located in Springfield, our state's capitol. The archives holds many valuable records for researchers, including census records, military records, vital records, and land records. Some of these resources can be searched online through one of the many databases provided by the archives. The Illinois State Archives will conduct some research for individuals while other things such as death certificate research, must be done in person.


Illinois Regional Archives Depository (IRAD)

The Illinois Regional Archives Depositories (IRAD) are regional branches of the Illinois State Archives system. Each region is made up of several counties and their records. IRAD branches are found in university libraries around the state. The record holdings vary between branches, but typically contain vital records, probate, land, tax, and mortgage records, municipal records, court records, election registers, and some City of Chicago records which pre-date the Fire.

There are seven IRAD branches in the state. Researchers can search the Local Government Records Database on the IRAD website to locate the branch which holds records for the county in which their ancestors lived. Searches can be conducted by the county in question or a record set title or by choosing the appropriate branch, if known.

If you do not live near the IRAD branch you would like to obtain records from, you can send them a letter with up to two requests. The turnaround time is usually within a month. There is a small copy fee for each request.


Illinois State Library

The Illinois State Library, located in Springfield, houses a vast number of resources in the form of books, maps, databases, and genealogy information.

Illinois State Flag

The Illinois State Library administers the Illinois Veterans History Project, which seeks to create a permanent record of those men and women who served our country and lived in Illinois. There is a patriot database that can be searched on the website listing information on those veterans who have already been entered. Forms can be downloaded from this website, completed, and mailed to the library for inclusion in the database. Once the forms are processed, the family receives a certificate of appreciation for their participation.

The library also hosts the Illinois Digital Archives, which is a repository of digital collections housed at the Illinois State Library and other Illinois institutions and libraries. Links are provided to the individual repositories and a search function is available to search for general keywords or themes. The collection hosts Illinois and Federal governmental documents, photographs, maps, newspapers, videos, oral histories, manuscripts and other materials relevant for both genealogists and historians. This collection can be used not only to locate family information, but also to gather social history information to add to a family's story.
