Search Kane County Genealogy Records

Kane County genealogy records date back to the 1830s and span birth, death, marriage, and land files held by the county clerk in Geneva. The clerk runs three offices across the county and hosts an online genealogy portal where you can search indexes from home. A fire in 1843 and a courthouse blaze in 1890 wiped out some early files, but many volumes were saved. If you have roots in Aurora, Elgin, or the Fox River Valley, Kane County is the place to start your search for family records.

Kane County Clerk Genealogy Records

The Kane County Clerk is the main source for genealogy records in Kane County. Marriage records go back to 1836. Birth and death records start from 1877. The main office sits at 719 S. Batavia Ave., Bldg. B, in Geneva, IL 60134. You can call them at (630) 232-5950 or send an email to CountyClerk@KaneCountyIL.gov. Two branch offices also serve the county. The Aurora office is at 5 E. Downer Pl., Suite F, Aurora, IL 60505. The Elgin office is at 2170 Point Blvd., Suite 600, Elgin, IL 60123. All three locations can help with record requests.

One thing to know about Kane County is that the clerk's office does not do research for you. You must search the records on your own. This is different from some other Illinois counties where staff will look up names on your behalf. If you can't visit in person, the online genealogy portal is your best bet. Walk-in visits let you browse indexes and order copies at any of the three office locations. Under the Vital Records Act (410 ILCS 535), birth records open for genealogy when they are 75 or more years old. Death records become available after 20 years. Marriage records open after 50 years.

A fire in 1843 destroyed part of the Kane County courthouse. Some record volumes were saved, but gaps exist in the earliest files. On March 13, 1890, about 5,000 court files burned in a separate fire. These losses mean that some pre-1877 records may be gone for good. If you hit a dead end with the clerk, try the Illinois State Archives or IRAD for backup copies of older Kane County records.

Note: The clerk's office will not do research on your behalf; you must search records yourself or use the online portal.

Kane County Genealogy Portal

Kane County runs a free online genealogy portal. You can create a free account to search, buy, and download genealogy records from home. The portal at genealogy.kanecountyclerk.org lets you look up birth, death, and marriage indexes by name and date range. This is one of the more useful county-level tools in Illinois because it lets you search and order copies without leaving your desk.

Search results on the Kane County portal show index data like names, dates, and record numbers. Once you find a match, you can purchase a copy through the site. Copies for genealogy get stamped with a note that they are for genealogical use only. The portal covers records within the time limits set by state law. Birth records must be 75 years old or more. Death records must be at least 20 years old. Marriage records must be 50 years old. Files that fall inside those windows are not available through the portal.

If you do not find what you need on the portal, try visiting one of the three clerk offices in person. Staff can point you to the right indexes, and you can browse volumes that may not yet be digitized. Keep in mind that the portal is a work in progress, so not every record has been scanned.

Kane County Land Records

The Kane County Recorder keeps land records that go back to 1837. These include deeds, mortgages, liens, and plat maps. You can search the online land records system at lrs.kanecountyrecorder.net. Records from 1977 forward are in the computer system. Older records require an in-person visit.

Land records are a strong tool for genealogy work. They show when a person bought or sold land in Kane County. Deeds list the names of the buyer and the seller, the date of the deal, and the location of the property. Mortgage files show financial ties. If your ancestor owned land in the Fox River Valley, these records can help you pin down when they lived in the area and where they were based. The Local Records Act (50 ILCS 205) requires that these types of county records be preserved for their long-term research value.

Kane County Genealogy at IRAD

The Illinois Regional Archives Depository for Kane County is at Northern Illinois University in DeKalb. The IRAD holds older Kane County government records that are no longer stored at the courthouse. This includes historical vital records, court files, probate records, naturalization papers, and more. Research at IRAD is free. You can call (815) 753-1807 to check hours and ask about holdings.

IRAD staff can handle mail and phone requests, but they limit each request to two names. If you have a long list of ancestors to look up, plan an in-person visit. You can take photos of documents for free. The IRAD holdings database lets you check what Kane County records are on file before you make the trip.

The Illinois State Archives in Springfield also has Kane County records in its statewide indexes. The marriage index covers 1763 to 1900. The death index covers pre-1916 and 1916 to 1950. These free online databases can help you find Kane County entries without leaving home. Under the Freedom of Information Act (5 ILCS 140), most government records are public, though vital records follow their own rules under the Vital Records Act.

Note: Out-of-state researchers who want the State Archives to search on their behalf must send a $10 prepaid fee.

Kane County Genealogy Fees

Fees for Kane County genealogy records follow state guidelines. The county clerk charges for copies of birth, death, and marriage records. Exact fees can vary, so contact the clerk at (630) 232-5950 or check the genealogy portal for the latest amounts. In general, Illinois counties charge around $10 to $15 for a first copy of a birth or death record. Additional copies cost less.

Genealogy copies are different from certified copies. A genealogy copy gets stamped to show it is for research use only. It cannot be used for legal purposes like getting a passport or updating a name. Certified copies are restricted to people who have a direct interest in the record, such as the person named or a close family member. The Vital Records Act sets these rules for all Illinois counties, including Kane.

• Birth and death genealogy copies: available when records meet age thresholds
• Marriage records: available after 50 years under state law
• Land record searches online: fees set by the recorder
• IRAD research: free for in-person visits
• State Archives out-of-state fee: $10 prepaid
