The only information I have about my gf Francisco Klosowski: he came into Brazil as a child. I don't know who came with him. There are lots ofUkranian and Polish Klosowskis near here but nobody can answer me this question. My great-grandfather was Kazimierz Klosowski. He was supposed to live from 1840 to 1880 in Poland or somewhere in that region of Austro-Hungarian Empire. Good luck! Renato.
