The county also has over 5 million land documents going back to 1844 in their eSearch system. Lake County sits along the Wisconsin border on the shore of Lake Michigan.

Lake County Clerk Genealogy Office

The Lake County Clerk is the main source for genealogy records in Lake County. The office is at 18 N. County Street in Waukegan. You can call (847) 377-2550 or email countyclerk@lakecountyil.gov. They hold birth records from 1871, marriage records from 1839, and death records from 1877. Those marriage records are among the oldest in the state, going back to before the Civil War.

Lake County has a free online genealogy search tool for pre-1916 records. You need to enter at least five letters of the last name to get results. The search pulls up an index that shows names and dates. Once you find a match, you can order an uncertified genealogy copy for $4 per record. That is one flat fee for any type of record. The Vital Records Act (410 ILCS 535) sets the rules for when records open for genealogy use. Birth records become available after 75 years. Death records open after 20 years. Marriage records are accessible for genealogy after 50 years. Lake County follows these state rules for all vital record requests.

This is the Lake County genealogy records search page at lakecountyil.gov.

The online index is a good starting point, but it does not cover every record the clerk holds. Some records are only in the books at the Waukegan office. If you don't find what you need online, try an in-person visit or mail request. Walk-in research lets you check the physical index books and ask staff for help with hard-to-find Lake County genealogy entries.

Note: The Lake County pre-1916 online index requires at least five letters of the last name to return results.

Lake County Circuit Court Records

The Lake County Circuit Court is part of the 19th Judicial Circuit. Court records are a key source for Lake County genealogy. Probate files show wills, estate inventories, and guardianship cases. Divorce records name both parties and often list children. Civil cases can reveal land disputes, debts, and other family details that don't show up in vital records.

Lake County has an eCourt portal where you can search court records online. This is the Lake County eCourt public portal.

The portal lets you search by name and case type. You can look for probate, family, and civil cases. Results show case numbers, parties, and filing dates. For older court files that may not be in the online system, you will need to contact the circuit clerk or visit in person. Some historical Lake County court records have been transferred to the IRAD at Northern Illinois University for long-term storage under the Local Records Act (50 ILCS 205).

One thing to know about Lake County: the naturalization books from 1856 to 1987 were taken by the state archives and are currently not available. This is a real gap for genealogy researchers who need immigration and citizenship records from Lake County. If your ancestor was naturalized in Lake County, you may need to check federal court records or the National Archives instead.

Lake County Land Records

The Lake County Recording Division runs an eSearch portal with over 5 million documents going back to 1844. That gives you nearly 180 years of land records for Lake County genealogy research. The Lake County eSearch portal uses the Cott Systems platform and lets you search by name, document type, date range, and more.

Land records tell you a lot about your ancestor's life in Lake County. Deeds show who bought and sold land. Mortgages show who lent money and the terms. Plat maps show lot lines and the name tied to each piece of land. These records can help you figure out where your family lived, when they moved, and sometimes who their neighbors were. Even if you can't find a birth or death record, a land record may be the one thing that proves your ancestor lived in Lake County at a certain time.

For very old Lake County land purchases from the federal government, check the Illinois State Archives public domain land sale database. That covers the original government sales across the state.
