I believe I am a descendent of the only Paech who lived in Zielona Gora, Poland - Krystyna Paech, she was my mother. Her father - Alfons Paech lived in Leszno, Poland. His family had roots in Berlin as far as I know and a lot of to do with Krotoszyn, Poland as well as Poznan, Poland. I do have a genealogy book compiled by my uncle and his wife (both based in the USA). As far as I know, majority of the alive Paech family is in North America (including myself) but some after the II WW briefly (15-20 years) resided in Australia. I am fluent in Polish and do travel frequently to central Europe.
