Linda from Pa: Thank you for anyhellp you can give me. I found out that my grandfather came to US as Friedrick Rothfuss. He lived in Newark, N. J. and married Karoline Dorothea(or Dorothea Karoline, who was called Dora) in 1890. She came from Germany with her siblings and parents, Jacob Friedrick Sieb and Marie Magdelena Sieb in 1883 or 1887. That's all I know about them.
