County of Arrival Records - Naturalization Records Pt. 5 If your ancestor naturalized after 1906, then your search will be easier. In 1906, the federal government stepped in to handle all naturalizations. All naturalizations after this date were processed by the supreme court of the county. Where do you find these records? More than likely, these records are still in the possession of the supreme court. You will need to contact the clerk of the court to request a search. Remember, the clerk of the supreme court is also the clerk of the county court! If your ancestor naturalized prior to 1906, then you have your pick of which court he naturalized in! Immigrants were more likely to naturalize in their local county court. You will need to contact the clerk of the court to request a search. Don't discount the city and federal courts though! How to determine which court before you start making phone calls?
