My grandfather's surname was Smolky, since all my relatives are deceased I need help with the surname. In doing research I have found several references to Smolky surname. I am wondering in what area of Poland they would have come from. All I can remember is that my mother told me it was a small town close to Lithuania. He immigrated into USA in 1882, of course, that would be Castle Garden records. I found his first paper for Naturalization but all it says Empire of Prussia. Any direction would be helpful. Thank you.
