I have all the MATECKI names you mentioned in your message in my family. It is hard to say who is who as the same names repeated very often in the families in the past. My MATECKI, my grandmother, came from Pogorzela, which town is about 50 miles south of the capital of Poznan. My family search is in the triangle Pogorzela-Wielowies-Kozmin. Glad to exchange documents if this is of your interest. Regards, Bernd from Germany. plonkab@onlinehome.de
