I have asked my parents and grandmother about names you wrote, but they don't know too much about it. They told me that probably our family from another city (Szczecin) should know more about our genealogy. The address you have - it is an address of a roman-catholic church. In Leszno (city where my parents live) there is about 30 Nadolnys. In Wroclaw, where I live, little bit less.
