I have found the naturalization record for Julius Schmaltz and it states that he was born in Lodz, Poland on June 9, 1876. He lists his race as being German but his nationality as Polish. He emigrated to the US from Hamberg, Germany and arrived in New York, NY on Spet 1, 1892 (didn't know what vessel he was on). Is there any way that I can dig into Polish archives and find his birth certificate? And is it common to be a German born in Poland? I was so excited to find this but now I don't know how to go any farther!
