Mahnomen County Courthouse Records

The Mahnomen County courthouse is the primary source for genealogy records in this county. Because Mahnomen County was formed in 1906 from Norman County, courthouse records begin that year. Birth, death, and marriage records from 1906 forward are held by the County Recorder. The Clerk of District Court maintains probate records, civil court files, and naturalization papers filed after county formation.

For ancestors in Mahnomen County before 1906, you need to look at Norman County records. That county, formed in 1881, covered this area before Mahnomen was split off. Norman County courthouse in Ada holds records for the period from 1881 to 1906. The MHS in St. Paul also has Norman County microfilm covering vital and land records from that era.

Land records in Mahnomen County start at the County Recorder from 1906. Original federal land patents for the area can be searched free at glorecords.blm.gov. Many parcels in this county were homesteaded or purchased through the federal land patent system in the late 1800s and early 1900s, predating county formation.
