Indexing Names

  • The naturalization records were usually filed in alphabetical order by surname.
  • In the Given Names and Surname fields, index only the names of the person who was naturalized. Do not index any other names that may appear on the form, such as the name of a parent or someone else who may have submitted an application in behalf of the person.
  • 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 Names: Georgios Or George
    • Surname: Broski Or Browzowski Or Brzozowski
  • Name variations were often noted at the bottom of naturalization records, with the name variation written above the signature of the principal and prefaced by a notation such as "Name Changed From." Click here for an example. Be sure to examine the record carefully for name variations, and index all name variations in the proper name fields, separating each variation with the word or.

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 1860 to 1989, almost 130 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 is 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 the 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.

Highlights and the Ruler

  • Highlights are not available for this project. You may use the ruler instead to follow a record across an image.
  • If you choose to use the ruler, please be aware that the ruler is not anchored to the indexing screen and does not automatically move as you move to a new entry. To use the ruler:
    • On the menu bar, click View.
    • Select Show Ruler.
