Great news!
As the Family History Library moves its microfilm holdings to the web, record sets are becoming newly available to logged-in FamilySearch.org users AT HOME. Naturalization records of our ancestors, including Declarations of Intentions and Petitions for Naturalization are coming online but many of them are unindexed, so will not come up in any search. To use unindexed records, look for record sets which contain original indexing on their pages, then, with a page or form number found for your ancestor, look at other record sets which contain the forms or record books.
Links to a number of record sets, for each Rhode Island county and the federal record index sets related to Rhode Island are available below. When using a record set on FamilySearch, click on the CAMERA icon to see the images; if the camera shows a LOCK, you will need to either log in or use the records in a Family History Library Affiliate Library. The links below are for FamilySearch microfilm, but note that the large sets for the federal and state records related to Rhode Island also are held on Ancestry.
It will take some trial and error to match an index entry with a record page; be sure you are looking at records for the same court (Common Pleas, Superior or Supreme) and if you cannot make a match, try inquiring at the State Archives. For federal court records (Circuit Court and District Court), the major indexing sets are now available online, linked below, and are very helpful, but for the full papers, inquire with the National Archives at Waltham, Mass.
The U.S. naturalization process is the path to legal citizenship for those who qualify and apply. The process included “first papers” or an initial statement of intention to become a U.S. citizen, followed, later on, by a final decree of naturalization. These petitions and decrees are court proceedings, so, the records are court records. Since the beginning of the United States, county, state, and federal courts have all been utilized for this process although after 1906, the federal government controlled it more tightly, but still not exclusively. All of those settings should be reviewed for the desired papers, but a general rule is to look at the court that might have been the easiest for your ancestor to access. Check the 1920 federal census for a year of naturalization (and other state and federal census years for year of immigration). Note that we may find American-born women in these records in the early 1900’s, as their citizenship was linked to their husbands’ for a couple of decades.
State and county naturalization records
Here is a guide to the pre-1950 naturalization records created in Rhode Island, and how to find them. In all cases you will need to find an INDEX entry, then try to find a petition or certificate FORM online (although those may not be available in every case). Read the record set descriptions on FamilySearch carefully, if available.
First, let’s use any index sets for state and county court records, usually sorted by county. I’ve included record sets of petitions, declarations and other Naturalization materials, for use after you have found a record in the index. I have maintained the record set names as used by FamilySearch.org even though they look a little confusing here. In some cases it will not be clear how to take the INDEX from a certain court and find the RECORDS for that same court; I would suggest really looking around and trying things.
