Illinois History

United States &gt; Illinois &gt; Illinois History

Effective family history research requires some understanding of the historical events that affected your family and the records about them. Learning about wars, governments, laws, migrations, and religious trends can help you understand political boundaries, family movements, and settlement patterns.

State, county, and local histories often contain biographical sketches of local citizens, including important genealogical information. This may be one of the best sources of information for some families.

Historical Content
County and local histories often contain biographical and historical information about residents and their families. They may provide the occupation, previous residences, birth date, or birthplace (city, county, and state or country).

Information about a family may be found in a history under the married name of a daughter or sister. Relatives or clues are often found by studying the pages that have biographies of residents or that tell the history of the town or township where an ancestor lived.

Histories are great sources of genealogical information. Many contain biographical information about individuals who lived in the area, including:

Local Histories
Some of the most valuable sources for family history research are local histories. Published histories of towns, counties, and states usually contain accounts of families. They describe the settlement of the area and the founding of churches, schools, and businesses. You can also find lists of pioneers, soldiers, and civil officials. Even if your ancestor is not listed, information on other relatives may be included that will provide important clues for locating your ancestor. A local history may also suggest other records to search. Local histories are extensively collected by the Family History Library, public and university libraries, and state and local historical societies.

The Family History Library, Salt Lake City, Utah has a sizable history collection for the state of Illinois consisting of two main types of records. First there are published histories of the state, its counties, and towns. They often contain maps, information on religious and civic organizations, and biographies of individuals and families who have lived in the area.

Second, there are copies of documents on microfilm and in published form that broaden a genealogist’s understanding of the times and places their ancestors lived in. Many of the documents include names of individuals involved in the event being documented.

A bibliography of older local histories for Illinois is included in:
 * A Complete History of Illinois from 1673 to 1884: Embracing the Physical Features of the County


 * A Reference Guide for Genealogical and Historical Research in Illinois A similar but less complete list is included in:


 * Manual for Illinois Genealogical ResearchGooldy, Pat, and Ray Gooldy. The source gives addresses of county courthouses, genealogical societies, and record repositories and gives Illinois locations of record categories such as census, land, military, and church records.

A few recent titles not in Wolf's list are in the Gooldy list.

State Histories Useful to Genealogists
Good genealogists strive to understand the life and times of their ancestors. In this sense, any history is useful. But certain kinds of state, county, and local histories, especially older histories published between 1845 and 1945, often include biographical sketches of prominent individuals. The sketches usually tend toward the lauditory, but may include some genealogical details. If these histories are indexed or alphabetical, check for an ancestor's name. Some examples for the State of


 * Historical Encyclopedia of Illinois Each volume focuses on a different county and contains historical and biographical information on that county. The Illinois State Archives has a biographical index to most of the Bateman volumes but may not have all volumes. Each volume of the collection is cataloged separately and can be found in the Family History Library Catalog by using a Place Search under:
 * ILLINOIS, [COUNTY]- HISTORY
 * ILLINOIS- HISTORY


 * Illinois: A History of the Prairie State.


 * The Centennial History of Illinois. Each volume has a different author and title representing a period of the state’s history. The Sesquicentennial History is an exact reprint of the original series. Some of the Centennial books are being microfilmed. To find the film numbers in the Family History Library Catalog, use the Author/Title Search under "The Centennial History of Illinois."


 * Collections of the Illinois State Historical Library. Each publication in this series of at least 38 issues is published under a different title.

Federal Papers Regarding Illinois
An important source with historical information about persons involved in the settlement of Illinois from 1800 to 1818 is:


 * The Territorial Papers of the United States Volumes 2 and 3 pertain to The Territory Northwest of the River Ohio, 1787–1803, which included present-day Illinois. Volume 7 contains The Territory of Indiana, 1800–1810, and volumes 16 and 17 contain The Territory of Illinois, 1809–1818.

The original records are in the National Archives.

The Draper Manuscript Collection
The Draper Manuscript Collection is a significant regional source that includes records of Illinois.


 * Draper Manuscript Collection The collection consists of nearly 500 volumes of manuscripts, papers, and books collected by Lyman Copeland Draper about the history of the trans-Allegheny West, a region including the western areas of the Carolinas and Virginia, all the Ohio River Valley, and part of the upper Mississippi Valley from the 1740s to 1830. The collection is divided into 50 series. Some series are titled by geographic area, some by the names of prominent frontier leaders, and some by topic. The bulk of the collection consists of notes from interviews, questionnaires, and letters gathered during Draper’s extensive travels and research to learn about frontier history. Personal papers are much more rare than government or military records.

The collection includes many items of a genealogical or biographical nature. For an inventory and partial indexes, see:


 * Guide to the Draper Manuscripts This guide gives series and volume descriptions for some of the Draper manuscripts. There are several indexes at the end of the book, including a name and subject index, an additional personal data index, and a list of references to Illinois.

Index to Lyman C. Draper Manuscripts. The name index gives the series and volume numbers, but is not complete.

Kaskaskia and Cahokia Records
Kaskaskia and Cahokia were important early Indian and French settlements. Their records include:


 * Kaskaskia Manuscripts, 1714–1816. These records were filmed at the Randolph County Clerk and Recorder’s office in 1975. These manuscripts were created by the early French Kaskaskia settlement in Randolph County. Records include tax lists, debts, wills, adoptions, land records, marriages, and selling of slaves. Most of this collection is in French and is not indexed. Some records have been translated into English and are indexed. A partial index to the historical records in this collection is:


 * Kaskaskia Records, 1778–1790 Collections of the Illinois State Historical Library, Volume 5. Springfield, Illinois: Illinois State Historical Library, 1909. (Family History Library book 977.3 B4i v.5; film 978493.) The preface states that a number of papers have been omitted from this work because "they are of a private character and add very little to knowledge of the history of the period."

The Raymond H. Hammes Collection maintained at the Illinois State Archives is an excellent collection of early land and other historical records from Kaskaskia in Randolph County and settlements along the Mississippi River, including the Cahokia settlement in St. Clair County, which at the time covered a large portion of present-day Illinois. Most of the Hammes collection has been microfilmed and can be found as 10 entries in the Family History Library Catalog in an Author/Title Search under the title Raymond H. Hammes Collection. It is indexed in Consolidated Index for the Raymond H. Hammes Collection cited in the "Land and Property" section.
