Ethel, what's the name of the book? I'm a DuBan living in Philadelphia and am trying to trace my roots back. I know my great grandfather Stephan (or Stephen or Stefan) was born in Vienna in 1851. He and his wife, Helen (Helena nee Moracvik (sp?)) and 2 children - Francis (Francisek) and Mary (Magdalena) came to America and lived in Philadelphia. Joseph, my grandfather, was their 3rd son and first of their family to be born in Philadelphia. Joseph was married twice. The first wife had 2 sons and their information is unknown. The second wife gave birth to my father and so goes my line. Unfortunately, I started my family tree project too late. My grandfather passed in May, so all of the DuBan family info he had is now lost.
