Greetings from France!
Hello Konrad. I see you have a family member from Kozmice, Osmanczik.
In my family tree there is PAULUS OSMANCZIK married to Catharina who has a daughter, ANNA. Born in 1761 in Kosmice. Anna has a brother, Jacob.And there are three other children. Anna later marries SiMEON KASPAR. Anna is the founder of my maternal line. And your family there?
Hopefully after such a long time gone by that posted here, you are still interested in telling me more.
