I don't know if we can help each other, but I am looking for relatives of my great grandma who came to America around 1856-7. I know she married John Pfeifer as soon as she got to Minnesota in 1858. I can't figure out who she came with, as it looks like the rest of her family died in Germany. Perhaps she was related to your Adam? She was from Wildpoltsweiler, or Steinenbach, both in Wuerttemberg and a short walk apart. Any connection?
