Posey County Quick Facts
Posey County Health Department Vital Records
The Posey County Health Department in Mount Vernon holds certified copies of birth and death records for events that took place in Posey County from 1882 to the present. This is your starting point for Posey County genealogy research involving vital events. Indiana did not begin statewide birth registration until 1907 and death registration until 1900. That leaves a window from 1882 to those dates where the county health department is the only official source.
Posey County is one of Indiana's oldest counties, formed in 1814. Its location at the confluence of the Wabash and Ohio Rivers made it an early entry point for settlers moving into Indiana. Families with Posey County roots can often trace lineages back to the early 1800s, and birth and death records from 1882 onward document those families across multiple generations. The health department in Mount Vernon is the first stop for any vital records genealogy search.
For genealogy-specific requests, the person named on the certificate must be deceased and over 75 years old. This requirement applies at both the county and state level. Bring identification and any proof of the ancestor's death when visiting the Posey County Health Department. Contact the office before visiting to confirm hours, fees, and whether an appointment is required. The Indiana local health department map provides current contact details for the Mount Vernon office.
Note: Fees for genealogy copies may differ from standard certified copy fees at the Posey County Health Department. Confirm the current rate before you visit Mount Vernon.
Posey County Clerk and Marriage Records
Marriage records for Posey County are at the County Clerk's Office in Mount Vernon. The clerk holds marriage licenses going back to Posey County's founding in 1814. Because the state marriage index only starts in 1958, the county clerk is the only source for any Posey County marriage before that year. The clerk's office is in the courthouse in Mount Vernon, and the original marriage documents remain there even for marriages after 1958.
Court records at the Posey County Clerk's Office are also valuable for genealogy. Probate filings, estate inventories, guardianship records, and civil case files from the 1800s and early 1900s contain family information that vital records do not include. An estate inventory from the mid-1800s can name a deceased person's surviving spouse, children, and other heirs. These records are publicly accessible under Indiana Code 5-14-3, which governs public records access in Indiana.
The Indiana State Library maintains a county research guide for Posey County that lists what records exist, where they are held, and what date ranges they cover.
