Collection Content
Early records were kept in register books beginning in 1877. By the early 1900s most events were recorded on pre-printed forms.

Legislation in 1819 required physicians to record births and deaths for their practices. Then, the physicians transmitted the information to their medical society which published the information in the newspapers. In 1843, a law was passed where relatives of a deceased person could appear before the clerk of the county commissioner’s court and report information regarding the death. The recording of vital records was voluntary until 1877 so few births and deaths were recorded. A fire in 1871 destroyed the Cook County Courthouse and nearly all previous records housed there. The few existing originals that were created by the county clerk may be found in the county clerk’s office or in one of the Illinois Regional Archives Depositories (IRAD).

In 1877, the State Board of Health was created to supervise registration of births and deaths. All births and deaths were to be reported to the county clerk by physicians. However, many were still not registered because the penalties for non-compliance were weak. In 1915, the state of Illinois gave the responsibility of recording births and deaths to local registrars who reported the information to the county clerk and the State Board of Health (now known as the Illinois Department of Public Health). By 1919, it is estimated that 95% of the population was recorded in the vital records.

How Do I Search the Collection?
To begin your search, it will be helpful to know:


 * The name of your ancestor.
 * The approximate date of death.
 * The place where the death occurred.
 * The names of family members and their relationships.

Search by Name by visiting the Collection Page: Fill in the requested information on the initial search page. This search will return a list of possible matches. Compare the information about the individuals in the list to what you already know about your ancestors to determine if this is the correct family or person. You may need to compare the information about more than one person to find your ancestor.

Keep in mind:
 * There may be more than one person in the records with the same name.
 * You may not be sure of your own ancestor’s name.
 * Your ancestor may have used different names, or variations of their name, throughout their life.
 * If your ancestor used an alias or a nickname, be sure to check for those alternate names.
 * Even though these indexes are very accurate they may still contain inaccuracies, such as altered spellings, misinterpretations, and optical character recognition errors if the information was scanned.

What Do I Do Next?
When you have located your ancestor’s record, carefully evaluate each piece of information given. These pieces of information may give you new biographical details that can lead you to other records about your ancestors. Add this new information to your records of each family.

I Found Who I was Looking for, What Now?

 * Use the birth date or age along with the place of death to find the family in census records.
 * Use the residence and names of the parents to locate church and land records.
 * There may be more than one person in the records with the same name.
 * You may not be sure of your own ancestor’s name.
 * Your ancestor may have used different names, or variations of their name, throughout their life.
 * If your ancestor used an alias or a nickname, be sure to check for those alternate names.
 * Even though these indexes are very accurate they may still contain inaccuracies, such as altered spellings, misinterpretations, and optical character recognition errors if the information was scanned.
 * Occupations listed can lead you to other types of records such as employment or military records.
 * The name of the undertaker or mortuary could lead you to funeral and cemetery records which often include the names and residences of other family members.
 * Compile the entries for every person who has the same surname as the deceased; this is especially helpful in rural areas or if the surname is unusual.
 * Continue to search the records to identify children, siblings, parents, and other relatives who may have died in the same place or nearby. This can help you identify other generations of your family or even the second marriage of a parent. Repeat this process for each new generation you identify.
 * When looking for a person who had a common name, look at all the entries for the name before deciding which is correct.
 * The information in the records is usually reliable, but depends upon the reliability of the informant.
 * Earlier records may not contain as much information as the records created after 1900.
 * There is also some variation in the information given from one record to another record.

I Can't Find Who I'm Looking for, What Now?

 * Check for variant spellings of the surnames.
 * Check for a different index. There are often indexes at the beginning of each volume.
 * Search the indexes and records of nearby counties.
 * One possibility why a person might not be found in the death records database is because there are missing certificates in this collection. The absent certificates are identified throughout the microfilm with a card stating the missing numbers. Since the actual certificates are absent from the microfilm they could not be indexed. Alternative indexes created by the Illinois State Archives could be helpful: 1916 and after www.ilsos.gov/isavital/idphdeathsrch.jsp or pre-1916 www.ilsos.gov/isavital/deathsrch.jsp. The pre-1916 index is a work in progress. Any certificate listed on these two sites can be ordered directly from Illinois Vital Records www.idph.state.il.us/vitalrecords/deathinfo.htm.
 * Contact the Cook County Clerk's Office www.cookcountyclerk.com/vitalrecords/deathcertificates/Pages/default.aspx.
