On this day in 1858 my 2nd great-grandfather Nicholas Conrad became a naturalized citizen of the United States. At least I think it was my Nicholas Conrad. The naturalization records of the mid-nineteenth century were not very detailed, so the best I can say is that a Nicholas Conrad from Bavaria was naturalized in Philadelphia within a logical time period and place for my 2nd great-grandfather having done so.
Nicholas swore his oath at the Court of Common Pleas in Philadelphia, Pennsylvania and renounced his allegiance to the King of Bavaria, officially becoming a United States citizen.
