Hello
Can you tell me if he was catholic or lutheran?
Catholic church records from Jaworzynka belongs to parish Istebna and records from this parish currently lies in civil registry office in Istebna, you can write them here: urzad@istebna.eu or here usc@ug.istebna.pl
You can also try to write to catholic parish in Istebna as they have indexed records, try to ask about baptism or marriage of his parents:
kominiak@poczta.onet.pl
Lutheran are online but i didnt found your father in there.
Greetings
Alex
