Dear Ms. Roccia,
Thank you for posting your request on History Hub!
We searched the National Archives Catalog and located Population Schedules for the 1920 Census; and the 1930 Census in the Records of the Bureau of the Census (Record Group 29). Digital images of the 1920 and 1930 census records are not available yet in the Catalog for parts of New Jersey or New York.
We also searched Ancestry and located for Maria Nicole Sibilia Devincenzo All Passenger Arrival results; All Death, Burial, Cemetery & Obituary results; in the 1920 Census; and 1930 Census. There may be a fee for using Ancestry. Instead, you may view these records online at one NARA's facilities for free via a NARA PC. For the nearest NARA location, please consult our web page at https://www.archives.gov/locations/. Also, some of the images from Ancestry are available for free on Family Search at https://www.familysearch.org/en/.
We hope this is helpful. Best of luck with your family research!
