Hi, Lenka!
Pogwizdow (Bochnia muncipality) records administratively belong to Krakow State archives. The metrics there contain data for 1890-1904 period. The other option is church metrics. Pogwizdow parish is a part of Krakow Diocesan, so the records are collected in either Krakow Diocese archive or parish itself. As I live and work in Krakow, it would be easy for me to access it. If you would, you can reach me on
