I did find this, if it helps.

Line 57

Shows a 16yr old Carrie Anderson (~1866) of Horseno, Denmark marrying a 25yr old Farmer named Charles C. Johnson (~1858) of Sweden in Stephenson, Menominee, Michigan on 05 Aug 1882.

Hmm... Could "Mary Johnson" be a fake name? Still doesn't explain the kids, unless there were more I don't know about.
