Guidelines for Requesting Records from OHS

Records prior to 1917, for years not listed above, may be found at one of the other Ohio Network of American History Research Centers, at a Latter Day Saint Family History Center, or in the probate court at the Greene County courthouse.

After 1917, Naturalization Records became federal-level records and are held at the regional Federal District Courts of Ohio and are held at the National Archives. Naturalization indexes, declarations of intent, and petitions will usually be in the NARA regional facility serving the State in which the Federal court is located. Some of these indexes and records have been microfilmed.

For listings of naturalization indexes and records available on National Archives microfilm, see listings for Record Group 21, Records of U.S. District Courts; Record Group 85, Records of the Immigration and Naturalization Service; and Donated Materials in the National Archives in Microfilm Resources for Research: A Comprehensive Catalog of National Archives Microfilm Publications (Washington, DC: National Archives and Records Administration, 1996).
