Nils A. Johnson was born Aug. 3, 1863, supposedly in Bergen, but that might not be accurate. His parent's names were Marie Ericksen (sp?) and John Johnson (sp?). He emigrated to the U.S. in either 1880 or 1890 - census records, etc. are in conflict. I can find no trace of him or his parents on the Norwegian databases on Ancestry. Any suggestions on how to proceed?
