Birth, marriage, and death records are connected with central life events. They are prime sources for genealogical information.
Illinois Department of Public Health, Division of Vital Records, 605 W. Jefferson St., Springfield, IL 62702-5097. It can take up to 6 weeks to get a vital record from Illinois.
A number of resources are available for individuals doing genealogical research using vital records filed in the state of Illinois. Births and deaths before January 1, 1916 and marriages before January 1, 1962 are recorded only in the office of the county clerk where the event occurred. Most county clerks have indexes to the records that are prior to 1916 that are available for the purpose of genealogical research. These indexes generally provide the name, date and place of occurrence and are located in county courthouses located throughout the state. Although self-service access to the indexes is generally permitted, the law limits physical access to the individual records to the clerk's staff. When you locate a record from the index, it will be necessary for the clerk to pull the record for you once you have paid the appropriate search fee. Please check with the county clerk for fees and policies on reviewing indexes.
