Washington County Genealogy Records

Washington County genealogy records are some of the oldest in Missouri, with marriage and land records going back to 1813. The courthouse is in Potosi, the county seat, which has been a center of lead mining since the early 1700s. Washington County was organized on August 21, 1813, from Ste. Genevieve County and was named for George Washington. It is one of the oldest counties in Missouri, and its records reflect a community with deep French Creole, Spanish colonial, and early American roots. The Washington County Library, the Washington County Historical Society, and a dedicated county genealogical society all serve researchers working on this distinctive part of Missouri history.

Washington County Recorder of Deeds

The Washington County Recorder of Deeds is at 102 N. Missouri St., Potosi, MO 63664, phone 573-438-4901. Marriage records go back to 1813 and land records to the same year. Washington County was organized in August 1813, making it one of the earliest counties in what is now Missouri. That means this office holds over 210 years of marriage and land documents. These are among the oldest genealogy records available in any Missouri county and are a vital resource for anyone tracing early Missouri families.

Washington County's early records reflect the complex settlement history of this region. French Creole families had been present since the 1700s, Spanish colonial land grants were issued before American territorial organization, and American settlers arrived steadily after the Louisiana Purchase. Land records from 1813 onward include some transactions that reference older Spanish and French land grants, which means the deed record series can take you back even further than the official county organization date. Marriage records from 1813 name both parties and the license date, and older records may list parents or witnesses. Military discharge records (DD-214 forms) for veterans are also held at the Recorder's office.

Standard Missouri fees apply: $24 for the first page and $3 per additional page. Document copies cost $1.00 per page. Marriage licenses cost $46.00 and require both parties in person with valid photo ID and a Social Security number. Licenses are valid for 30 days statewide with no waiting period.

Note: Call 573-438-4901 before visiting to confirm current hours and discuss access to the oldest record volumes.

Washington County Court Records

The Washington County Circuit Clerk maintains court records for the 23rd Judicial Circuit. The courthouse is in Potosi. Court and divorce records date from 1814, just one year after the county was organized, and probate records go back to 1827. For genealogy researchers, these files are extraordinarily deep. Probate records from 1827 onward name heirs, identify family relationships, describe estates that may include mine shares and land grants, and record the distribution of assets. Given Washington County's lead mining heritage, some probate files document estate assets that include mining rights and equipment, which adds a distinctive dimension to the record.

Civil court records include divorce cases, debt matters, guardianship proceedings, and land disputes. Naturalization records for immigrants who settled in Washington County are held by the Circuit Clerk. Washington County attracted miners from Cornwall, England, and from German and Irish communities in the mid-1800s, and naturalization records from those groups can provide birthplaces, emigration dates, and ship arrival information that is essential for tracing immigrant ancestry. The Old Mines community in Washington County also preserves a French Creole heritage, and records from that community are among the most distinctive in Missouri genealogy.

Cases filed after November 12, 2003 are available at no cost on Missouri Case.net. For older records, visit the Potosi courthouse or contact the Circuit Clerk.

Note: Juvenile records are sealed under Missouri law.
