I am glad that I noticed this early post of yours.
My gg gf John Daniel Johnson came to the US from Denmark, I found him first in Lucas County, Iowa where he marries Caroline Castline (Casterline) Phillips in that county about 1870, they move later to Beloit area in Kansas, then they reverse and move to Douglas County MO. We have never been able to determine why or to what specific enterprise he wished to participate. He had worked for the railroads in Kansas.
We had some early ancestors notes about him having possible cousins in the US with the surname Larson. But have never found anything about that further.
This is the first that jogged my memory about this little tidbit.
do you happen to know anything about their location in Denmark before entering the US?
