Morawietz, Maliglowka and Przybylok are quite common names in the area west of Tarnowskie Góry (parishes of Stare Tarnowice and Strzybnica – USC districts of Stare Tarnowice and Piaseczna). However, I haven’t connected these names to my family tree yet.
Either way, before 1887, Rybna was part of the parish of Stare Tarnowice; after that, it belonged to the newly-founded parish of Strzybnica. For both parishes, records can be found online. http://www.christoph-www.de/kbsilesia2.html
The USC recording Rybna events was the USC Piaseczna.
