I wonder what else of your family is from Germany, stems from german stock! :)
" The generic Polish term for a coat of arms, herb, dates from the
early 15thcentury, originating as a translation of the Czech erb, which in turn came from the German Erbe - heritage." We had kinghts before 15th century ...:)
en.wikipedia.org/wiki/Battle_of_Cedynia
"The Battle at Cedynia (also Cidini, Cydyna, Ceden, Cedin, Zehden) occurred on 24 June 972 during the rule of Duke Mieszko I, the first Christian ruler of the Polans (later Poland). There was a war raging over the western border of the young country, because Mieszko wanted to capture the lightly defended and economically important estuary of the Oder River, in order to secure influence in Pommerania. "
You know you can tell me alot and this coat of arms means nothing to me but most importantly what has that to do with Kopernikus???
I have name with -ski and I am not German I am from original branch of this clan.
Going back to Kopernik you choose Polish citizen pick on him and claim him to be German, you change his name and tell us lets share him because ... I don't see the reason to do it. I don't understnd why Poles should do it, some people in Poland have this name (more than in Germany) now somebody tells us to share him. Why? Maybe we should label citizens "25% German, 50% Lithuanian etc." Even they don't know about their 12,5% of lets say Czech blood.
It is stupid and Germans wouldn't like to do so when it comes to them.
