Orland Park Genealogy Quick Facts
Orland Park Vital Records
Orland Park does not have a local vital records office. Birth, death, and marriage records for Orland Park go through the Cook County Clerk Bureau of Vital Records at 118 N. Clark St., Room 120, Chicago, IL 60602. The phone number is (312) 603-5656. You can make requests in person, by mail, or through VitalChek for certified copies. Genealogical copies must go by mail only.
Cook County records for births and deaths begin in 1871 and 1872. Orland Park was a small farming community in those early years, so you may find fewer records from that period compared to areas closer to central Chicago. Marriage records are also on file with the county clerk. Birth and marriage copies cost $15 for the first and $4 for each extra. Death copies run $17 first and $6 after that.
The Vital Records Act (410 ILCS 535) sets the rules for when records open up for genealogy use. Births must be at least 75 years old. Deaths must be 20 years old. Marriages must be 50 years old. Once a record meets those age rules, anyone can request a genealogical copy by mail. These copies are stamped as uncertified and cannot serve as legal ID.
Orland Park Library Genealogy Resources
The Orland Park Public Library is a solid starting point for genealogy research in the south suburbs. The library provides free in-building access to Ancestry Library Edition, which covers census records, immigration records, military files, and millions of family trees. HeritageQuest is available too, and you can use that one from home with your library card. Both of these databases are key tools for tracing Orland Park family roots.
The Orland Park Public Library website lists its research databases and hours of operation.
Beyond the databases, the library has staff who can help with basic genealogy questions. If you are new to family history research, the reference desk is a good place to start. They can walk you through how to use Ancestry, how to read census forms, and where to find Cook County records online. Some libraries in Cook County also hold local newspaper archives on microfilm. Check with the Orland Park library to see what newspaper collections they may have for the south suburban area.
State Records for Orland Park Genealogy
The Illinois Department of Public Health keeps statewide birth and death records from 1916 to the present. If the Cook County Clerk does not have the record you need, IDPH is your backup. The IDPH genealogy page explains how to request genealogical copies. All genealogy requests must go by mail. Processing takes around 12 weeks, and there is no way to check the status while it is in progress.
IDPH charges $10 for a genealogical birth record and $10 for a genealogical death record. These are lower than Cook County fees. The trade-off is the long wait time. For Orland Park residents who can drive to the Cook County Clerk office in Chicago, the walk-in option is almost always faster.
The Illinois State Archives has free online databases that are useful for Orland Park genealogy. The Statewide Marriage Index goes from 1763 to 1900. The Death Index covers two periods: 1916 to 1950 and 1951 to 1972. Public domain land records are also searchable. All of these are free to use from any computer.
Court and Archive Records
The Circuit Court of Cook County holds probate records, divorce records, and naturalization petitions. The Cook County court portal lets you search some of these online. The court archives at 50 W. Washington, Room 1113 in Chicago have over 500,000 naturalization petitions from 1871 to 1929. If your Orland Park ancestors came from another country, these records can show where they were born, when they arrived, and other details that vital records might not include.
The IRAD depository for Cook County sits at Northeastern Illinois University at 5500 N. St. Louis Ave., Chicago, IL 60625. IRAD preserves older local government records, including vital records, land deeds, and probate files from Cook County. Under the Local Records Act (50 ILCS 205), these records are maintained for long-term public access. You can submit up to two name lookups per mail or phone request at no cost. Call (773) 442-4506 to check current hours.
Note: Suburban Cook County death records from 1910 to 1915 have gaps, so check both county and state sources for that period.
