For immigrants who arrived in the 1890s or later, modern naturalization records can be the best documentation of their foreign home. Sometimes ship passenger lists are missing, or immigrants are difficult to locate or recognize on the arrival lists. However, naturalizations that took place after 1906 are not difficult to find and, with them, you can fully identify the immigrant and the family. This assures you that, once you find a record, you can be certain whether it pertains to the correct family or not. This lesson only discusses naturalization records created after 1906. A future lesson will cover the information found, and search procedures for earlier naturalization records. However, before you begin searching for these records, we need to cover a few basics, such as when and how they were created, as well as who you are likely to find in the records. Of course, you will want to know the content of these records, for, as you will read below, their content is every researcher's dream!
