I have done extensive research on my father in law Ostap Kabluckyj b 1927 -
this may or may not be the same for you as it was for me
Ostap Kabluckyj b 1927 - Rogahtyn in Poland - Rohatyn in Ukraine ...SAME village
Although my father in law was born in Poland it became Ukraine and just before WW2 the Russians invaded Ukraine - there was /is a stretch of land on the Polish and Ukraine border which changes ownership regularly - Poland -Ukraine-Poland -Ukraine etc
SO - when WW2 started and Hitler was at war with RUSSIA - thousands of men from this area of Poland / Ukraine signed up to fight WITH Hitler against Russia because they wanted the Russians out of their country - Ukraine .(at that particular time )
This Regiment - 14th Waffen - Grenadier SS Division was later posted to Italy - where many were killed or wounded - my father in law was wounded ...anyway in 1946 after the war this group of soldiers were given a choice
3 years as Prisoners of War in either England / Scotland / Wales /Canada / Australia / New Zealand
( all countries of the British Empire ) or they could return to The Ukraine - whereupon they were informed they may be shot as Traitors by the Russians for fighting for Germany ...
their 3 years as prisoners were working on farms growing food for local communities .
my father in law came to England along with 46,000 others . he never returned home for fear of being shot .

http://www.rootschat.com/forum/index.php?topic=573780.0so - my suggestion is that although he was born as a Polish citizen -did his town became Ukraine and he possibly fought with the Germans - and became a POW ??
VERY VERY few of the thousands who were POW's and settled in English Empire countries told their families they fought FOR the Germans - but MANY did and I quite understand why my Father in Law did - because he wanted the Russians out of his town - simple as that .
so if you get Rogatyn /Rohatyn / up on a map of Ukraine and see how far it is to the Poland border and maybe Slupski is a name around those parts .
have a look at this tree - may help in the area of Poland ??
