Genealogy / Want to find a person [762]

Hello, I'm from Croatia and i had a pen friend from Poland somewhere between 1980-1985. In the meantime i moved and lost every contact with him.

It's been 30 years and I would love to find him but all I have is this old address:

Ryszard Patok
WOJ:GDAŃSK, 84-107 STARZYNO-118

Please if anyone knows anything about this man,let me know :) thank you!
