For records before 1910, Pennington County was carved from Red Lake County and other predecessor counties. If your ancestor was in the area before 1910, check Red Lake County records and the Minnesota Historical Society for pre-formation materials.

• Birth records from 1910 (County Recorder; MDH for certified copies)
• Death records from 1910 (County Recorder; MDH from 1908 statewide)
• Marriage records from 1910 (County Recorder; MOMS index online)
• Burial records from 1910 (County Recorder)
• Land records from 1910 (County Recorder)
• Military records from 1910 (County Recorder)

• Will records 1911-1982 (FamilySearch Catalog)
• Federal census records 1910-1940 (FamilySearch, Ancestry)
• State census record 1905 (MHS, predates county formation)

The 1905 Minnesota state census was taken before Pennington County was formed, so ancestors in the area would appear under the predecessor county (Red Lake County). The FamilySearch wiki for Pennington County at familysearch.org lists all available digital collections.

Minnesota Historical Society and State Resources

The MHS Gale Family Library (345 Kellogg Blvd W, St. Paul, 651-259-3300) holds naturalization records, state census materials, newspaper collections, and pre-1910 land records for the Pennington County area. The library is open Tuesday through Saturday. Many materials must be used in person. The MHS is the key source for records before Pennington County was formed in 1910.

The MHS regional center serving northwest Minnesota is in Moorhead. Call the MHS main line to ask which Pennington County collections are held regionally versus at the St. Paul library. For a newer county like Pennington, some pre-formation materials may only exist at the state level.

Federal land patents before 1908 are free to search at glorecords.blm.gov. These records predate Pennington County's formation and would be listed under predecessor county names. The Minnesota Genealogical Society at mngs.org offers additional databases and tools for Minnesota family history research.
