Some people appear more than once in these records. If your ancestor’s name appears more than once, check each record to make sure you find all of the information that you can.

Broaden your search by selecting the “name variants” box in the search bar. This will return a larger number of records including those with similar names, alternate spellings or the use of initials or middle names.

If you chose to include the naturalization year or birth year in you search and you are having trouble finding your ancestor, try increasing the year range. Naturalizations could take place years after an immigrant arrived in the country and birth years were sometimes recorded inaccurately. Expanding the year range will return more results and may lead to surprising new details.
