Thank you Zlatica, that's a good suggestion about Ellis Island, I didn't look at that, knowing that none of this family went to USA. That's not to say that maybe Wenzel's siblings might have gone to USA though.
Wenzel's wife's name was Antoria Anna but no, I don't know the maiden name as yet. I see that you gave the spelling of Wenzel as Wencel and Vencel, are they more likely true spellings than the one I've got.Just for interest can I ask in what country you live and if you are Czech, hope that's not a rude question.
