I cannot help with your research, but you are wrong in the message board. East
Prussia is hundreds of miles away from Gurkow, which was in County Friedeberg in the Neumark area of the Prussian province of
Brandenburg, ca. 50 km east of the
Oder river and the city of Frankfurt/Oder. Frankfurt/Oder is
German, but the
Oder river is the German-Polish border. All areas east of the
Oder river are part of Poland today. The areas west of the
Oder river are
German and part of the federal state of
Brandenburg.
Today Gorkow/Gorki Noteckie is part of the town of Zwierzyn.See "

Here is the address of the administration, but I cannot say whether they understand English:
Gmina strzelecko-drezdenecki,
ul. Wojska Polskiego 8,
66-542,
Zwierzyn,
