Rohan/Sablatura in Frenstat

My family is from the Village of Frenstat, Czechoslovakia. Frantisek (Frank, Franz)Rohan married Mariana Sablatura on 24 Sept 1878. Frantisek set sail for America in 1880, leaving his wife and small son to come to Fayette County, Texas at a later date. He came on the ship Nurnberg and arrived in New Orleans 11 Nov 1880. Mariana Rohan and her young son, Frantisek, born 1879 set sail for America in 1881. I have not found the ship list that names them, but enroute, young Frantisek died. I have information that the parents of Frantisek Rohan b 1854, were Jan and Josefa Ocko Rohan. I would like to verify that information. They did not come to America but stayed in Frenstat. Also, Mariana Sablatura Rohan’s parents were said to be Frantisek and Anna Hilser Sablatura also of Frenstat. Again, I would like confirmation that they were indeed, Mariana’s parents. I have also been told that Jan Rohan’s father was Ondrej Rohan b 11 Jul 1785 and his mother was Anna Adamcik,married on 17 May 1807. Ondrej Rohan’s parents were said to be Jakub and Barbora Cervenka Rohan (married 7 Jul 1782) . Who were Jakub and Barbora Cervenka Rohan’s parents? Also, it would help if I had the names of siblings, as well. I am planning a trip to the Czech Republic and will be visiting Frenstat. If family still lives in or near Frenstat, I would like to meet them.
