Census Records and Additional Sources

Federal census records for Koochiching County begin with the 1910 census, as the county was not formed until 1906. The 1910, 1920, 1930, 1940, and 1950 censuses all cover this county. These records list every person in each household by name, age, birthplace, and relationship. For a county formed as recently as 1907, the early censuses are especially important because they may capture the founding families of each community.

Minnesota state censuses were taken in 1905. Koochiching County was not yet separate in 1905, so residents then living in what is now the county would appear under the predecessor county or territorial area. This is worth noting when you are tracing families who were in this area before 1907. Earlier census years would list these residents under Itasca County or the surrounding areas.

Naturalization records matter for Koochiching County research. The county drew workers from Finland, Sweden, Norway, and other parts of Europe to work in the paper mills and logging industry. Naturalization files at the county courthouse can reveal exact birthplace, date of entry into the United States, and other details that point back to records in Scandinavia. Some of these records are available on microfilm at the MHS and some have been digitized through FamilySearch.

Local newspapers from International Falls and surrounding communities have been preserved on microfilm. Obituaries, marriage announcements, and birth notices from these papers often contain more detailed family information than the official records. The MHS library holds microfilm collections of Minnesota newspapers. Contact the Historical Society and the public library in International Falls to ask about what local papers they hold and for which years.
