I am a g.g.grandaughter to Rudolph. He came to Americaia in 1852 or so. His first wife died in New York and he remarried Katherine Mueller. He had a son Rudolph from the first wife. The rest of the children, Christain, Adam, Catherine, August, Mina, and Herman were from the second marriage. I am trying to locate his parents from Germany or Switz. His wife Katherine was born in Bavaria, we think. He settled in Manttowoc Co., Wi. If anyone has info I would love to hear from you.
