I see a mixed breed trying to deny his german roots and being more polish than the pure Poles! :)
I,m not cross breed my family has been living in this country for 1000 years (the most propably much for longer). I have the same Y-DNA (I1a) as 18% of Polish people 23% of German people and 50% of Swedes.
Soldier in the "PREUSSISCHER BUND", bones identified as those of Kopernikus, NOT as polish - GERMAN!
Well it is nice example of Prussian Bund :
en.wikipedia.org/wiki/Germanization
Oletzko County was a historic East Prussian county with its capital at Oletzko. The county was populated by Mazurs, a Polish ethnic group. In the process of Germanisation, the proportion of Polish-speaking people declined steadily:
1818 - over 90% of population
1852 - 65%
1861 - 58%
1890 - 46%
1900 - 33.5% (German census)
I have my opinion about eastern Germans talking about being ancient Slavic or ancient Germanic etc ...
