Dear Mr. Daropoulos,
Thank you for posting your request on History Hub!
We searched the National Archives Catalog and located the series titled Declarations of Intention for Citizenship, 1865- 1971 in the Records of District Courts of the United States (Record Group 21) that may include entries for the person you are looking for. Some of these records have been digitized and are available using the Catalog. For more information about this series and the non-digitized records, please contact the National Archives at New York (RE-NY) at firstname.lastname@example.org.
Prior to September 27, 1906, any "court of record" (municipal, county, state, or Federal) could grant United States citizenship. Often petitioners went to the court most geographically convenient for them. As a general rule, the National Archives does not have naturalization records created in state or local courts. However, a few indexes and records have been donated to the National Archives from counties, states, and local courts. Researchers should contact RE-NY at email@example.com to determine if records from lower courts are available. In certain cases county court naturalization records maintained by the National Archives are available as microfilm publications. Records from state and local courts are often at the state or local archives or historical societies. We suggest you contact the New York State Archives and since Kings County is part of New York City, the New York City Department of Records and Information Services.
Due to the COVID-19 pandemic and pursuant to guidance received from the Office of Management and Budget (OMB), NARA has adjusted its normal operations to balance the need of completing its mission-critical work while also adhering to the recommended social distancing for the safety of NARA staff. As a result of this re-prioritization of activities, you may experience a delay in receiving an initial acknowledgement as well as a substantive response to your reference request from RE-NY. We apologize for this inconvenience and appreciate your understanding and patience.
We hope this is helpful. Best of luck with your family research!
