I don't know if I can help you but my grandfather came over with his mother in late 1800's. I do not know her maiden name. His name was Frank Pokorny. He was born in a town North of Prague, Usti nad Labem. His father, my great-grandfather, was also named Frank and came to the United States first with the daughter, Mildred (my grandfather's sister, whom I have spoken to in 1979 when she was in in her 80's). They settled in the Bonx, New York City. The sister grew up and married a Victor Christof and the two families lived in a two story building. My grandfather married Irene Spacek. She died when my father was three in 1917. He remarried and there was a another son, Adolf born. My father's father then died when my father was twelve and so he moved upstairs and was raised by his Aunt Mildred and Uncle Victor Christof. In 1943 my father married Emily Madeline Deise.
