I am looking for immigraton information about John Seethoff. He was born in Germany in 1848, and his name there was Johann Saathoff. Family story is that his last name was mis-spelled during immigration, and became Seethoff in USA. He started using John within a few years after arriving in USA. The 1st public record I can find is in DuPage County Illinois, and Barrington, Cook County, Ilinois. He spent most of his adult life in New Salem, Morton, ND. He died in Metolius, Jefferson, Oregon in 1918. I am interested in anything related to John's immigration: arrival date; arrival port; whether he had 2 brothers with him; whether the Northern Pacific Railroad was a part of his travels; did the Northern Pacific own or arrange the boat; did Northern Pacific RR give free land.
