There is a fellow by the name of David Kraus who has done a lot of research on the Kraus family. I believe he has the information you seek. He traced the Krauses from Germany to Russia to the US. I've lost touch with him, but as I recall, he was living in Pennsylvania some years ago. He attended a Kraus family reunion in Hutchison, Kansas, a few years ago, which is where most of my Kraus relatives landed.
