Hi,
The address on Sienkiewicza Street (ul. Sienkiewicza) has been in the Morgi location for years. Morgi is near Brzezinka and, of course, Brzęczkowice, but it is not the same area.
I have found something interesting for you. Under this link, you can find an old map that shows the Polish vs. German names of streets. Indeed, Sienkiewicza Street was called Goethestraße.
I hope that it will be usefull for you.
