I have a Jilek thread in my family history also beginning in Bohemia, Czech Republic. I don't recognize the names that you have in your family history, sorry I can't help. However, I can tell you where my relative Jake Jilek (later changed to Yelick) was from and maybe that will give a clue where to try to locate ancestors. Jake Jilek was orginally from the area known as Susice, very near the German border. This area was known for basket weaving and for making of a charcoal like substance, I also have relatives named Aschenbrenner from that area. Good luck Rebecca
