I am looking for information on my grandmother's brother. His name was Andrew Prokop but he changed it to John LeFall. There was no known contact between him or his siblings after the name change. His parents were Fred and Katherine Prokop. I believe his last known place of residence was in Indiana. He would have been born in the early 1900s (in the teens or 20s I think). Any info would be greatly appreciated.
Thank You.
