THE MEANING AND RESEARCH OF MY POLISH LAST NAME, SURNAME? [4500]
1. Are Prussian's part Russian, Polish and German?
Here is some infos about Prussia: en.wikipedia.org/wiki/Prussia
2. Is "unka" or "Yonka" a Russian or Polish or German name
I have never heard of the name Unka (I am Polish). I did some search online and i am pretty sure it's not polish name. On the website of Rada Jezyka Polskiego they wrote that the name is not present in any sources containing the list of names (old or the newer ones).
Yonka - maybe it should be Janka? If Janka then it's Polish.
3. "Prain" both from Prussia?
It doesnt sound Polish at all. Most likely German.
