Stephen,
Hi, sorry this has taken so long. Did you email me already? I was sure you had, but can't find it! I do have your Eliza in my stuff and actually have an old email from someone looking for a Lillian Wendelschafer who lived in Pipestone, MN. I suspect your Lillian is that one. My mom grew up a stone's throw from the Wendelschafer Cemetery on the adjoining farm. I have virtually nothing on the Trost side. Frederick and Catherine were the original parents who emigrated with their kids. Their is also an Adam and Augusta buried there who are about the same age. I think Adam and Frederick are cousins. I have a copy of some research done professionally in Germany in the very early 1980s on the Wendelschafer side. The Trost side was looked into but no specifics found. The german genealogists said it is an extremely common name. I do have locations for certain things which might help narrow down a search, but have been unable to do any myself. I will look at your site and send to you what I have. Thanks, much!
