Illinois Genealogy Resources
The availability of land attracted many immigrants to America and encouraged westward expansion. Land records are primarily used to learn where a person lived and when he or she lived there. They often reveal other family information as well, such as the name of a spouse, an heir, other relatives, or neighbors. You may learn a person’s previous residences, his occupation, if he had served in the military, if he was a naturalized citizen, and other clues for further research. You may learn a person’s previous residences, his occupation, if he had served in the military, if he was a naturalized citizen, and other clues for further research.
The county or town offices that maintain land and property records often have plat books containing maps of property boundaries and land ownership within the county.
The United States has been divided into sections called quadrangles by the United States Geological Survey (U.S. Department of Interior, Geological Survey, 1200 South Eads Street, Arlington, VA 22202). The USGS has produced highly detailed topographical maps showing physical and manmade features in each quadrangle. These maps are available at most university libraries.
Once a parcel of land was transferred from the government to private ownership, it may have stayed in the family for generations or for only a few months. It may have been subdivided, sold and resold, with each transaction creating new records. These person-to-person transactions are an important resource to the genealogist. The potential for an ancestor to be recorded is high. These records may offer genealogical clues, such as the given name of the wife, a previous residence, names of children, or death information. Land records also offer clues to maiden names if a father deeded property to his daughter upon marriage. Witnesses and neighbors may also be in-laws or relatives. It is important to trace the purchase and sale (or the acquisition and disposition) of each parcel of land an ancestor owned.
The original records are filed in the county clerks’ or recorders’ offices or in IRAD depositories. As new counties were formed and boundaries changed, transactions were then recorded in the new county, while the parent county retained the records previously created. The Family History Library has microfilm copies of most of the county records and is continuing to microfilm deeds of other counties up to about 1900. Contact the county clerk or recorder for records that have not been microfilmed.

Illinois Public Land Purchase Records - Land sales from the
Illinois public domain were recorded by a variety of persons
employed by the federal, state or local governments. The records
in this database were transferred to the Illinois State Archives
and detail the sale of over 54,000 square miles of public land.
Each entry includes the purchaser's name, purchase date, number
of acres, price per acre, and in some cases the purchaser's sex
and residence. Researchers will find information regarding over
538,000 land sales from the 19th Century. For those seeking
ancestors from Illinois, this can be an extremely helpful source
