Hello there! I don't know if you are still following this thread, but, my Grandparents were the 2 Serecins from Svinica on the Ellis Island registry that you mentioned. George, my Grandfather came to the US alone, prior to my grandmother, Elizabeth (Koza), who came to the US in 1934 with my Father Vincent and Uncle Frank. How cool that someone was looking into this! Can I help you with info?
