Knox County Genealogy Records
Knox County genealogy records are some of the oldest in Indiana, rooted in Vincennes, the state's oldest city and a place where European settlers arrived long before Indiana achieved statehood. Birth and death records at the county level go back to 1882, and marriage records at the clerk's office reach far deeper into the 19th century. If you are searching for Knox County family history, this guide walks you through the local offices, state resources, and online tools that can help you find what you need.
Knox County Quick Facts
Knox County Vital Records Office
The Knox County Health Department in Vincennes is the local office for birth and death genealogy records. Records at the county level run from 1882 to the present, giving researchers access to well over a century of vital data. Knox County is one of Indiana's original counties, formed in 1790, which means its records predate those of most other counties in the state. That history makes it a particularly rich place for genealogy research.
For birth and death records from before statewide registration began, the county health department is your first stop. Indiana did not begin keeping statewide birth records until 1907, and statewide death records until 1900. Knox County vital records from 1882 onward fill that gap. The health department staff can help you identify which records exist for a specific individual, though you will need to show proof of your relationship or, for genealogy requests, demonstrate that the person named is deceased and over 75 years old as required under Indiana state rules.
Contact the Knox County Health Department by phone or in person at the Vincennes courthouse complex. The local health department map at in.gov/health/lhd/local-health-department-map/ lists current contact details and hours for the Knox County office. Hours can change, so it is worth calling ahead before making the trip.
Note: State rules require that a person named on a death or birth certificate be deceased and over 75 years old before a genealogy requester can access that record without showing direct family relationship.
Genealogy Records at the Knox County Clerk
The Knox County Clerk's Office in Vincennes holds marriage records going back to the county's earliest days. Because Knox County was established before Indiana statehood in 1816, its marriage records can trace families through the territorial period. This is a significant resource for anyone researching ancestors who lived in the Wabash Valley region of southwest Indiana.
The clerk's office also holds court records including probate filings, guardianship records, and estate settlements that can help place ancestors in Knox County across generations. Probate records often name multiple family members and can fill in gaps that vital records leave open. The recorder's office handles deeds and land records, which are another strong source for tracing when and where ancestors lived in Knox County over time.
Under Indiana Code 5-14-3, the Access to Public Records Act, most court and land records held by county offices are public documents. You can request copies in person at the clerk's office in Vincennes. Staff there can guide you toward the right record books for the time period you are researching.

Indiana Archives and Knox County Historical Records
The Indiana Archives and Records Administration (IARA) in Indianapolis holds older Knox County court records that have been transferred from the county. IARA is at 6440 E 30th St and can be reached at (317) 591-5220. Because Knox County is one of Indiana's oldest counties, some of its earliest court and probate records may have been microfilmed or transferred to IARA's permanent collection over the years.
Under IC 5-14-3-4, records that are classified as confidential become available 75 years after their creation, with some exceptions for adoption and medical records. This rule opens up older Knox County records to genealogy researchers who might otherwise be blocked. IARA's online catalog at researchIndiana.iara.in.gov is a good place to check what Knox County materials they hold before making a trip or request.
