I know that those names given by someone as an example are not Jewish names in Poland, those are regular Polish names.
With the help of Polish "patriots," a la Ziem most outlandish lie will be excepted as truth if repeated countless times by master manipulator Lyzko and readily confirmed by know all Ziem. Of course, you know less than nothing, about anything, especially country of your birth, so don't try to comment unless you ask Ziem first
To stir an sh*t, Lyzko throws the bone of contention in the form of perfectly Polish names, claiming their Jewish origins, just because ending with WICZ instead of SKI, They assume the name is Jewish. WICZ may indicate the name originated in eastern regions of Poland, but not necessarily. Not one Brylewicz in the whole Old Testament.
The majority of Jewish names in Europe were borrowed; of course, Ziem knows better, because he knows.
