I'm looking for relatives in Buenos Aires. All I know is that unckle of my grandpa Jan Sadowski immigrated to Argentina. He was born 2(8).09.1907 in Siemiuny, now it's Belarus, but it used to be Lithuania and Poland. I know that he had children and Italian wife. So I want to find relatives to communicate with them because they should know that they have big family in Belarus and Poland which is looking for them. Please, if you know any Sadowski in Buenos Aires, write to me. Thank you for your help.
