Step-by-Step Illinois Research, 1880-Present

Illinois Step-by-step research 1880--present

Step 1. Find out everything possible from living relatives and their family records.
Every good genealogy project starts with finding all the clues that can be gathered from living relatives — both from their memories and from documents or memorabilia in their homes.

What are the best questions to ask?
In order to extend research, ask for names, dates, and places. Everything about who a relative was and when and where they lived is a clue to a new record search. For ideas, see :
 * 50 Questions to Ask Relatives About Family History


 * Creating Oral Histories

What documents should be collected or copied?
Because these records cover names, dates, places, and relationships, they are a valuable source of clues. Look for them in your home, your parents' home, and ask living grandparents to check for them.

Step 2. Find ancestors in every possible census record, 1850-1950, online.

 * A census is a count and description of the population for a given date. A census took a "snapshot" of a family on a certain day.
 * For each person living in a household (depending on the year), their name, age, birthplace, relationship to head of household, place of birth for father and mother, citizenship status, year of immigration, mother of how many children and number of children living, native language, and whether they were a veteran of the military can be listed.
 * Searching for a family in census records every ten years can identify all the children in a family.
 * Searching in earlier census records to find someone as a child can identify parents.

Using clues to lead to census record searches.
Here is the family in the 1920 census, with baby Robert Holtz and 11-year-old sister, Edna Holtz. Their parents are Louis W. and Frieda Holtz. Studying the birth years of their children, it is apparent that they were already married in 1910. The next goal would be to find them as a young married couple in 1910. - Here is the family in the 1910 census, living in Chicago Heights, Cook County, Illinois. This record says that Louis W. Holtz came to the United States in 1888.

-

Look for ancestors in as many censuses as possible. Use the clues from each census for hints where to find families in both earlier and later census records.
- For more information, see Illinois Census and United States Census.

Step 3: Find birth, marriage, and death certificates for ancestors and their children.
States, counties, or (even towns in some states) recorded births, marriages, and deaths.
 * In addition to the child's name, birth date, and place of birth, a birth certificate may give the birthplaces of the parents, their ages, and occupations.
 * A marriage certificate might list the parents of the bride and groom.
 * A death certificate may give the person's birth date and place, parents' names and birthplaces, and spouse's name.

Using the census clues to lead to a birth certificate.
Census information gives approximate birth years and probable birth places, and that information leads to finding important birth records. In addition to basic birth date and place, a birth certificate can give age, birthplace, occupation, etc. about the parents.

Using the census clues to lead to a marriage certificate.
Finding marriage records can:
 * establish the full identity of the wife, with her maiden name and possible birth details.
 * find the names of the parents of the bride and groom.



Using the census clues to lead to a death certificate.
Moving forward in time, older generations stop showing up in the census. That is a clue that they probably died in the last 10 years. The death certificate is important because of all the possible secondary data beyond just the date and place of death:
 * birth date and place of the deceased
 * maiden name of the wife
 * names of the deceased's parents
 * birth places of the deceased's parents.

-

Many of the examples shown here are index entries. That means for each of them an actual, original, full certificate exists. It is highly advisable to order the original certificate. It will contain many details not given in the index. In some cases, the image of the original is found online. Instructions are given below on obtaining the original certificate in other cases.

How to Find the Records
There are basically three ways to find these indexes or full original certificates:
 * online databases
 * writing to a county courthouse (prior to the beginning of state civil registration)
 * purchasing them through the mail

Records at the County Courthouse.
These records were originally created by county clerks, and then copies were sent to the state. County clerks can be willing to help find all the birth records for one family or perform other searches that the state would not do. To contact county clerks by e-mail or telephone, go to the Wiki article for each county. Links to the county Wiki articles are found at the end of this page or by clicking here: Illinois Counties.

Order Certificates from Illinois Vital Records Department.
Almost always the full original certificate will contain information not contained in the index. Although it costs money, consider sending for the full original certificates, particularly for direct line ancestors (grandparents, great-grandparents, etc).

Step 4: Try to find additional details about ancestors in obituaries, cemetery records, and Social Security records online.

Step 5: Search military records: World War I and World War II draft cards.
There are many different types of military records: draft records, enlistment records, service records, pension records, etc. Information in military records can vary from a simple lists of name, age, and residence, to more detailed records including name, residence, age, occupation, marital status, birthplace, physical description, number of dependents, pensions received, disabled veterans, needy veterans, widows or orphans of veterans, and other information. - Example of a World War I draft card. - Example of a World War II draft card.

Step 6: Look for church records online.
Church records function as vital records. Church records are particularly helpful prior to the advent of civil registration.

 * Many, if not most, people are married in a church, and then a record is created by the minister.
 * Likewise, ministers presided over funerals, then creating a burial record, which documents a death.



Search for church records that can provide additional birth, marriage, and death information.
