The office is located in the Marshall County Courthouse on the town square. Hours run Monday through Friday, 8:00 AM to 4:30 PM. Copies cost $0.25 per page under the state Open Records Act.
The Court Clerk is a different office that keeps marriage, divorce, probate, and general court files. Marriage records start in 1907 and are open to the public. Probate and divorce files also date from that year. Marshall County belongs to Judicial District 22, which includes Johnston and Bryan counties as well.

What Marshall County Records Show
Marriage records from the Marshall County Court Clerk list both names, ages, and often parents' names. The officiant and date are also recorded. These files start in 1907 and are public. Marriage records are one of the best genealogy tools because they connect two family lines in a single document.
