Illinois, Cook County Deaths - FamilySearch Historical Records

What is in This Collection?
This collection consists of a name index to deaths for Chicago and Cook County, Illinois. It covers the years 1878 to 1939 and 1955 to 1994. 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.

 * If you cannot locate your ancestor in the locality in which you believe they lived, try searching records of a nearby town or county
 * Try different spellings of your ancestor’s name
 * Remember that sometimes individuals went by nicknames or alternated between using first and middle names
 * One possibility why a person might not be found in the death records database is because there are missing certificates in this collection.
