Genealogy / THE MEANING AND RESEARCH OF MY POLISH LAST NAME, SURNAME? [4500]

KEYOWSKI
I think the original might have been Kijowski. It sounds that way.
This surname would mean "a man from Kijów (Kiev, the capital of Ukraine, once having a notable polish minority).

and since I am here, I will ask someone for their opinion about
TESSARSKI / TASSARSKI / TASARSKI surname.

The family comes from Ukraine.

Thanks for explaining Tessarski surname. I forgot that I've already found the meaning years ago. It doesn't have to be of czech origin, though: I have, by accident, found a polish document from 1520's or so (in latin but with many polish words), which uses word "thesarz" for a carpenter, so the word might have been used for carpenters in old-polish :)

I have some other questions, if I may
