Naturalization and Immigration Records at the Pennsylvania State Archives

Colonial Naturalizations
The Archives maintains naturalization lists of the Supreme Court and Courts of Nisi Prius (Record Group-21) for the years 1740-1773. These lists consist of names of those people who swore an oath of allegiance to the British Sovereign. Arranged chronologically, these lists were published in Pennsylvania Archives , Second Series, Volume 2 and have been reprinted as Persons Naturalized in the Province of Pennsylvania, 1740-1773 (Baltimore: Genealogical Publishing Co., 1967), with an index.

Pennsylvania Supreme Court Naturalizations
In addition, naturalization records of the Supreme Court of Pennsylvania, 1794-1868 (Record Group-33) are available for the Eastern District (Philadelphia), Southern District (Chambersburg), and Western District (Pittsburgh). The records cover the period 1794-1868 and usually contain only the following information: person's name, country of former allegiance, date of petition, and affidavit of acquaintance. An index of the records of the Eastern District in Philadelphia covering the years 1794-1868 has been published in Philadelphia Naturalization Records: An Index to Records of Alliens' Declarations of Intention and/or Oaths of Allegiance, 1789-1880, in the United States Circuit Court, United States District Court, Supreme Court of Pennsylvania, Quarter Sessions Court, Court of Common Pleas, Philadelphia (Detroit, MI: Gale Research Company, 1982)

To conduct a naturalization search:

1). Determine where the individual was naturalized. If the immigrant was naturalized in Philadelphia, consult Philadelphia Naturalization Records . This index covers records from five courts: the Court of Common Pleas (CP), Court of Quarter Sessions (QS), United States Circuit Court (CC), United States District Court (DC), and the Pennsylvania State Supreme Court (SC). If the final date of naturalization includes a notation of SC, these records will be held by the State Archives.

The Index supplies the following information: the person's name, the country of former allegiance, the court where he applied, and the date(s) of the declaration of intention and/or oath of allegiance. Copies of pages from this index may be obtained from the Historical Society at the aforementioned address, and it is available for research on microfilm at the Pennsylvania State Archives, Harrisburg.
