Sorry I am just replying as I just saw the reply now (sad but true).
My Sadileks were in the Chicago area. Vincent Sadilek Sr came from Bohemia in 1887 and then met my Great Grandmother, Barbora Simunkova in Chicago and married her in 1889.
They stayed in Chicago/Cicero, Illinois until settling in Berwyn, IL in 1924 until they passed away.
I believe one of the pictures you have posted on your ancestry tree page is a photo that I have the original of (Of John Sadilek, and wife Barbara) My grandmother was awesome at keeping all the photos that the Sadilek side of the family had. I have many from when they took two separate trips back to their homeland for visits.
I would love to find out if somehow the Nebraska Sadileks are related to my Sadileks in Chicago.
