Naturalization Records

How to Locate Naturalization Records in northwest Ohio

For the following years, naturalizations were handled by the following courts:

Beginning to 1856: Court of Common Pleas

  • Declarations of Intention may be available, filed separately
  • Naturalization Records are usually found in the Journal of the Court of Common Pleas
    • Records in this case simply list the names of those being naturalized and that they took the oath of citizenship

1856-1906: Probate Court

  • Declarations of Intention are filed separately, either loose files or bound volumes
  • Naturalization Records are filed separately in bound volumes
  • Minor records are for those who were under 18 years of age when they arrived in the US.
    • No declaration of intention was required. Witnesses support the facts. Search these records if the other records locate nothing.  Be careful to note from 1885-1906 whether the records are “NR” (naturalization record) or “MR” (minor record), as these have a separate series of volumes.

1906-1930s: Court of Common Pleas

  • Declarations of Intention may be filed separately, either loose files or bound volumes
  • Naturalization Records are filed separately in bound volumes.  The form is sometimes called “application and certificate of naturalization”.  Attached material may include a certificate of arrival, a declaration of intention, and other documentation.
  • Federal courts gradually began to take over the process during this period and many counties do not have naturalizations after 1906.
