Hi Gerry,
a sister from my father married Hermann Friedrich Karl KULOW, in Lüttenhagen, Mecklenburg, in 1919. Later they lives in Waren, Mecklenburg. I looked on this side

and now that there is a little town named "Krakow". I think is Klatzow maybe Krakow.
I hope it's a little bit help.
Best wishes
Birgit
