It is interesting that Torkil's brother Erik should be back to 'visit'? for the 1875 Norwegian census. Erik and two younger siblings, Tron and Gunhild, had sailed for America (destination - St. Paul, Minnesota) in April of 1869 from the port of Oslo. Tron became a naturalized US citizen and was still residing in Minnesota at the time of the 1920 US census (71 yrs old then). He used the name of the old family farm in Krosherad/Sigdal as his surname - Rishof.
