Indexing Names

  • The indexed cards were usually filed in alphabetical order by surname.
  • In the Given Names and Surname fields, index only the name of the person who was naturalized. Do not index any other names that may appear on the form, such as the names of witnesses, judges, or family members.
  • Titles and terms are not indexed in name fields.
  • If alias names were included on a naturalization card or if an individual’s name was listed with various spellings on the card, include all variants, separating each with the word Or. For example, if a name was written as "Georgios (George), George Broski, George Browzowski, or George Brzozowski," you would index the name fields as follows:
    • Given Name: Georgios Or George
    • Surname: Broski Or Browzowski Or Brzozowski

Indexing Dates and Ages

  • If the age of an individual was recorded but not a birth year, do not index the age in the Birth Year field, and do not calculate a birth year based on the age.
  • If a birth year was recorded for an individual but not the age, do not calculate the age based on the birth year and the naturalization year.
  • This collection is an index to the original immigration documents and records. The index covers a collection of records that date from 1818 to 1954, almost 136 years. When the index cards were created, the dates were often recorded without the century being noted, for example 05-13-75. Many cards do not contain enough contextual information to indicate whether the date referred to the 1800s or the 1900s. If not enough contextual information is available on the card to indicate the century (such as the individual's birth date or other information), do NOT assume a century, which could misrepresent the facts of the document; just index the year as a two-digit number instead.

Diacritics and Other Characters

  • If the name of a person or locality was written with a character not on your keyboard, such as the ò in Nicolò, please insert the character by clicking on the Enter special international characters icon (which is a square with an "ñ" in it) and selecting the character you want to insert, or:
    1. On the menu bar, click Edit.
    2. Click International Letters.
    3. Click on the letter you want to insert.

Corrected or Crossed-Out Information

  • When information was crossed out and then replaced, type the new data in the appropriate fields.
  • When information was crossed out, was not replaced, and can be read, type the crossed-out information.
  • If information was not crossed out but was replaced or was added to, type the most complete version of the record.
  • When the information was crossed out, was not replaced, and cannot be read, mark the field as unreadable by pressing Ctrl+U.
  • When every entry on a record cannot be read, mark the entire record as unreadable by pressing Ctrl+Shift+U.
