I know it's been a couple years since this was posted, but I do have some of the information you are asking for from a couple of sources.
I have just recently located and have been conversing by email with Morris
Knorr, the author of "German/Catholic
Courage. From the steppes to the Prairies, The Life and Times of Adam
Knorr 1870-1952".
He also has another book available. To quote a recent email "Last summer my wife and I travelled with 2 Scheck's back to Grosswerder Ukraine where our family came from. I've written a history of Grosswerder with many pics. etc."
I don't have the books yet, but I have arranged to have the first one reprinted and to purchase a copy of the second one.
As for Eva's siblings, I have that and quite a bit more of the family tree from a different source, whom I'm also hoping to get in touch with soon. Looks like they had a very large family!
