Collection Time Period
Cook County has recorded marriage records since 1871, the year of the Great Chicago Fire. A few miscellaneous records exist prior to July 1871.

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

Record Content
Key genealogical facts found in most Illinois marriage records are:


 * Name of bride
 * Name of groom
 * Ages of both bride and groom
 * Towns of residence of both bride and groom
 * Date license was issued
 * Date marriage was performed
 * Name of person officiating at the marriage

After 1916 the following information was added:


 * Birth date of bride and groom
 * Full names of parents

How to Use the Records
Begin your search by finding your ancestors in the index. Name indexes make it possible to access a specific record quickly. Remember that these indexes may contain inaccuracies, such as altered spellings, misinterpretations, and optical character recognition errors if the information was scanned.

When searching the index it is helpful to know the following:


 * The place where the birth, marriage, or death occurred.
 * The approximate date the event occurred.
 * The name of the individual or individuals such as the names of the bride and groom, the infant, or the deceased.

Use the locator information found in the index (such as page, entry, or certificate number) to locate your ancestors in the records. Compare the information in the record to what you already know about your ancestors to determine if this is the correct person. You may need to compare the information of more than one person to make this determination.

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. For example:


 * Use the marriage date and place as the basis for compiling a new family group or for verifying existing information.
 * Use the birth date or age along with the place of birth of each partner to find a couple's birth records and parents' names.
 * Use the birth date or age along with the place of birth to find the family in census records.
 * Use the residence and names of the parents to locate church and land records.
 * Occupations listed can lead you to employment records or other types of records such as military records.
 * Use the parent’s birth places to find former residences and to establish a migration pattern for the family.
 * The name of the officiator may be a clue to their religion or area of residence in the county.
 * Use a marriage number to identify previous marriages.
 * Compile the entries for every person who has the same surname as the bride or groom, 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 been born, married, or died in the same county 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.

Keep in mind:


 * 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.

If you are unable to find the ancestors you are looking for, try the following:


 * 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.

Record History
Marriage returns were submitted to the county clerk by the minister or justice of the peace who performed the marriage. Most of these records were also destroyed by the fire in 1871. Only a few marriage records exist prior to the fire. Couples were not required to obtain a marriage license until 1877. A statewide register of marriages was started in 1962 as county clerks forwarded marriage information to the Illinois Department of Health. A few marriage records have markers shaped like spades that indicates records with document numbering problems. When searching the collection displays a image with such markings, a second search might yield an unmarked marriage record with a new number without spades.

The Cook County Clerk's Office issues certified copies of Cook County marriage records for events that occurred in Cook County, Illinois.

Why This Collection Was Created?
Marriage records were created to legalize marital relationships and to safeguard the interests of the wife and other legal heirs.

Record Reliability
