Chicago Delayed Birth Index, 1871-1948

Lookups available
Digital images of index pages. $2.00 for the first scan/surname; $1.00 each for additional scans. (If the lookup will exceed $5.00, I will check with you before going ahead with it.)

Request this lookup if you didn't find an entry in the Cook County Birth Index, 1871-1916 and want to see if the birth was recorded through delayed birth registration, probably in the 1940s.

If the surname covers more than 4 pages it is better. cost-wise, for you to order the delayed birth index film through your local Family History Center. The index is not alphabetical by given name and so it's not possible for me to send pages for a specific given name.

About delayed birth registration
Delayed birth registration provided a way for births that weren't reported at the time of the event to be officially registered. Many people obtained delayed birth certificates during the 1940s in order to apply for Social Security or Railroad Retirement benefits. (See http://www.ancestry.com/learn/library/article.aspx?article=11202 )

If you are able to locate a copy of a delayed birth certificate, it may include notes on what documents were used to prove the birth. These notes may provide the name of a physician or midwife, the name of a church where a baptism took place, and/or the names of friends or relatives.

It is available on seven microfilms which can be requested through any Family History Center.

Alphabetical by surname (with some exceptions, e.g., "Simons" might come before "Simon" or they might be interfiled) but not by given name

Why search this index?
If you aren't able to find an individual's name in the Cook County Birth Index, 1871-1916, you may be able to find an entry in the Chicago Delayed Birth Indexes which will provide a birth date and evidence that the birth occurred in Chicago.

How to find copies of delayed birth certificates
I am told that at least some of the delayed birth certificates can be obtained through the Cook County Clerk's Office for a fee. One researcher who did this successfully told me that it took 2-3 weeks to receive the document.

To the best of my knowledge, Birth Corrections and Delayed Births, 1916-1918 are the only records of this type available through the Family History Library system.

Search tips
Because the index isn't strictly alphabetical, be sure to look just before and after the surname you are searching to catch entries in unexpected places.
