Your first port of call should be the
www.kresy-siberia.org website which also has a helpful Yahoo group. A few things spring to mind..."Buguslaw" is probably "Boguslaw" (pronounced "Bog-oo-swav") and the family would have been deported to Siberia by the Red Army after the Russians invaded the eastern part of Poland, known as "Kresy" (Germany taking the wsetern part).
The family would therefore have been living in the east of Poland. Skarburski sounds like an ethnically Polish name and so the father, although born in "Germany", would have been an ethnic Pole perhaps from a part of Poland that became Germany or a part of Germany that is now Poland. Complicated!
The Siberia experience for so many Poles is an epic story with much material available. If you want further help, let me know your email address.
