Name
A spelling variation doesn’t mean you’ve found the wrong person: immigrants often Americanized their names either before or after naturalizing. Some indexes note alternate names, too, so look carefully.
Certificate number, volume, page and other court identifiers
While you won’t learn your ancestor’s eye color here, these details will help you request the record from an archive.
Title and location of court
Where your ancestor’s naturalization took place — key in locating the original naturalization file.
Country of birth/allegiance
Add these details to your searches at Ancestry to help you locate your ancestors in other record collections. Also, your ancestors may have belonged to a group, lodge or church in their U.S. town associated with their homeland or nationality.
Date
Naturalization indexes typically include the date of naturalization, and will sometimes also include date of birth and the date the immigrant arrived in the U.S.
Date and place of arrival
Invaluable in locating a passenger list, but remember that an ancestor may have traveled to and from America more than once, so look at all possibilities.
Names and addresses of witnesses
Friends, neighbors, cousins, coworkers, in-laws and other acquaintances may have witnessed your ancestor’s naturalization. Research these names to see if they’re related in some way or share ties to a church, neighborhood or occupation; also try these names when you can’t find your own ancestor in the census — they could be living nearby.
- Prior to the Naturalization Act of 1906, naturalizations could take place in any court of record – local, state, federal and sometimes even in criminal or marine courts. After 1906, naturalizations were processed in federal courts, although some local courts continued beyond that date.
- Pre 1906, a wide variety forms used in naturalization often varied from court to court; so did the quantity of family history information contained within each.
- U.S. federal census records from 1900 through 1930 can help narrow down the time period in which an immigrant filed citizenship paperwork; the 1920 census also asked for the year of naturalization. Census abbreviations used are Na, for naturalized citizen; Pa, when only First Papers had been filed; and Al, meaning the alien had yet to start the naturalization process.
- Non-native-born males in the 1870 U.S. census who checked the column labeled “Male citizens of the U.S. aged 21 years and upwards” would have been naturalized prior to 1870.
- Sometimes there’s nothing more than a Declaration of Intent — not all immigrants completed the naturalization process.
- From 1790 to 1922, wives of naturalized men automatically became citizens as did any alien woman who married a U.S. citizen. From 1790 to 1940, children under 21 automatically became naturalized citizens upon the naturalization of their father.
It wasn’t so simple to become an American citizen. Aliens were required to file paperwork, meet residency requirements, and wait and wait and wait. The following steps show how it all played out in a paper trail — one you can trace.
Step 1. Declarations of Intention (or First Papers). Normally First Papers were completed soon after arrival in the United States. An alien needed to wait at least two years before moving onto the next step, although if the alien waited more than seven years, First Papers had to be refilled and the waiting period stared over again. After 1862, honorably discharged U.S. veterans were excused from this step.
Step 2. Petition (Second or Final Papers). Naturalization Petitions were formal applications submitted to the court by an alien following the mandatory waiting period, during which time the alien was also required to maintain residency in the United States for at least five years with the final six months in the county in which Second Papers were filed. Waiting periods often meant that aliens would file First Papers in their town of arrival and Second Papers in the town they later migrated to.
Step 3. Certificates of Naturalization. When the alien completed all citizenship requirements, a Certificate of Naturalization was issued making the alien a citizen of the United States. Certificates of Naturalization would remain with the person as proof of citizenship. Other documents remained with the court where Second Papers were filed.
“I hadn’t thought much about researching the Italian side of my family. I knew most of the basic facts: my grandfather, Lou, had come to America as a teenager with his parents and siblings and lived in New York City for the rest of his life. Unlike my other family lines, which were riddled with name changes and homes and relationships in constant states of flux, Lou’s family was easy to find – they were predictable, almost boring. Inadvertently, I guess I was ignoring them.
Then one day I happened upon Lou’s naturalization record. In it was his birth date, when and where he and his first wife (one of those in-flux family lines) were married, his hometown, an old photo and his signature, which I recognized from birthday cards he’d sent when I was a kid. And the kicker: an address.
I searched it on the Internet and got a current look at the apartment house – the same one where my mother was born. I also discovered and ordered a 1939 tax photo of the residence. Now I have a clearer view of both history and present day. I also have the encouragement I need to ensure I won’t ignore Lou and his wonderful Italian family ever again.”
