Naturalization Records

The Suffolk County Naturalization Project

Members of the Italian Genealogical Group along with members of some of the other Long Island genealogy groups have completed the task of computerizing the naturalization records that are in the care of the Suffolk County Clerk’s Office.

The earliest records are from 1853 and continue up to 1990 when the process of naturalization was turned over to the Federal government. The complete database has over 68,000 names.

Among the records are 49 petition books containing over 12,000 names of military personnel that was processed at the U. S. Army base, Camp Upton.

Camp Upton was constructed on what is now the Brookhaven Labs in Yaphank, Long Island. Thousands of men were trained there during the period of 1917 to 1918. Most of the men were from the metropolitan New York area but many were from states as far way as California and Washington State. This was especially true of those men that were processed for discharge after the war ended in November of 1918. At this base Sgt. Irving Berlin, wrote the famous army song, "How I hate to get up in the morning".

Included in the listings are the names of three Army nurses that were naturalized at Camp Upton. We don’t usually think to look for women in military indexes. The names of the military personnel are from all over the United States, thus making this database very important to researchers from outside the New York area. If a researcher cannot find the naturalization papers for someone who served in World War One in his local area, it is necessary to check the Camp Upton records.

A special thank you to the people listed below who came forward and gave of their time and talents to make this project possible. Some drove out to Riverhead and to help copy the indexes or to do the proofreading of the final results. Others typed the names into a database and e-mailed it to the project coordinator. A few who are not even genealogist but saw the value of the project and helped copying, typing or proofreading.

A very special thank you to Don Eckerle, who without his computer savvy, this project would never have been completed. Don was able to fix our mistakes, convert the different programs that our volunteers used and create the database into a useful research tool.

Database Search

Three methods of searching are provided. The first search uses only the surname field; the second search uses both the given name and the surname fields. The third search is to help expand the selection to include the names that begin with certain letters.

Entering Fe in the Partial Family Name field finds all names that start with the letters fe such as Fettinget, Fey, Ferling, Feller, etc.

Entering the letter B in the Partial Given Name field finds all names that start with the letters B such as Barbara, Barry, Bob, etc.
