I just had a genealogist in Vilnius research y family history. I show this:
About 1780 ? Michal (Mykolas) Kwietkowski married Magdalena Purenaite . She probably died and he married Kotryna Stankiewicz. Michal was a nobleman. He had a son Jan (Jonas ) who was born in Lithuania.
The dates may be too far back for you.
I had my DNA done and uploaded it to Gedmatch so if you did so, we might show as DNA cousins.
My email is
lovetuscansun@yahoo.com if you have further questions.
