Hi Heidi,
I did a quick look and it looks like your Peter Rausch and my Balthasar Rausch were brothers. I have lots of Rausch and Utsch information and photos. I am in the midst of preparing for my daughter's graduation but will keep in touch. It has been many years since I have received any new information. Is there anything specific that you are looking for? I am really trying to find adoption info on Tillie. I think I also have a copy of a oral history of the Rausch's coming to America. I will check.
