Iver Johnson

This I have but can't seem to find that ships passenger list..."From "Hawkeye Heritage, Vol 25:3 ( Autumn 1990) page 164-165. Iver Johnson Date and Port of Arrival, 1885, New York City, age 18. Passengers from Prussia, Denmark and Norway. Ship India, Christianson, destined for Iowa. Source page 165, Source Code 7671. I probably have to go back to the Iowa site, but maybe some of you can give me some help. I have him documented from North Dakota to present bu that New York/Iowa connection has me stumped. Pat
