Montana Naturalization and CitizenshipEdit This Page
From FamilySearch Wiki
Naturalization records have generally been filed in the county and district courts of Montana. You can write to the clerk of the court and request a search of indexes to certificates of arrival, petitions, declarations, and final naturalization papers.
The Family History Library has copies of some Montana naturalizations. The National Archives—Pacific Alaska Region (Seattle) has documents for:
- The four territorial district courts (1868-89). (Indexes on FHL film 1490886 items 1-8.)
- U.S. district courts in Butte (1894-1929), Great Falls (1924-26), Helena (1892-1929). (FHL films 1492066 items 1-4 and 1490886 items 11-27.)
- The U.S. Circuit Court (1891-98). (FHL films 1490886 items 9-10 and 1492068 items 1-20.)
To obtain records since 1906, contact the federal office of the Immigration and Naturalization, which you can find in the federal office building nearest to you.
