Hello! My name is Kira Bonk and I think that we may be related somehow. My great-great grandfather was Franciszek Ksawery Bak, and he was born in 1884 and lived near Gorlice, Poland. He came to America and then Chicago (I'm not sure the dates yet). I think we may be related because he named his children many of the names you mentioned- Bruno, Edward, and Walter (Walter was my great-grandfather). Please email me so we can see if we are connected somehow, that'd be wonderful!
