Warsaw
Best when the family place is in Mazovia, west of Warsaw, or scattered across archives, parish towns, and newer civil records.
- Civil records office: start with the local USC if the record is still in civil-registry custody.
- Parish records source: use the Warsaw archdiocese directory when the line runs through church books instead of civil offices.
- Archive search: use Warsaw as the archive-facing city when the locality trail is broader than one office.
- Nearby record towns: Sochaczew, Lowicz, Grodzisk Mazowiecki, and Płock.
