Hi. I am looking for more information on my grandparents and great grandparents. My grandfather is Joseph Sobotka and my grandmother is Sophie Tworek-Sobotka. My grandfather died in about 1934 in Chicago, IL when my father was just 5 years old. My grandmother died 1 year later. Therefore, we have very little information about our ancestory. We believe that my grandfather immigrated to the US from Poland. Any help would be greatly appreciated. thank you.
