The Philadelphia City Archives has declarations of intention and petitions for naturalization which were filed in the city and county courts only between 1790 and 1930.
The Archives does not have the records of the United States Circuit and District Courts of Philadelphia, the Supreme Court of Pennsylvania, or the records in any local court outside of Philadelphia county.
Note: There are exceptions to this, owing to mistakes made by the W.P.A. and not corrected by Filby. The principle exception is that entries marked "DC" between 1860 and 1870 are most likely records filed in the Philadelphia County District Court, which are in the City Archives' possession.
All names in the W.P.A. and Filby's have either one or two entries following them. The price for naturalizations at the City Archives is based upon a complete set of papers (declaration and/or petition). Therefore, please remit only one fee for each set of papers.
The fee for a set of papers is $ 5.00, payable to the "City of Philadelphia"
Our address is:
Philadelphia City Archives
3101 Market Street
Philadelphia, Pennsylvania, 19104
The fee of $5.00 is for a search of the records and copies, if the records exist. Otherwise, a certificate of no record will be sent.
Owing to a decision made by the court officers in the 1930s, only the declarations of intention of the Quarter Sessions Court were indexed, not the petitions. There may still exist a possibility that your ancestor petitioned the Philadelphia courts for citizenship.
Most naturalizations which have occurred in Philadelphia since 1897 were done in the United States District and Circuit Courts. Please contact the National Archives, Mid-Atlantic Regional Branch, 9th & Market Streets, Philadelphia, Pennsylvania, 19107 (215-597-3000) for instructions on researching those records.
