My Nelson family as well settled in Culbertson but came from Norway. My grandpa, David S. Nelson, came with his wife Josephine Johnson, and started homesteading in Culbertson around 1910 I think. My dad Dave Nelson Jr. was born there in 1921. Several brothers came over around 1920, some on separate boats. So my granddad had several brothers around the area. One I know for sure was Clarence Nelson. There was also Mina and Martha int his family but I believe they kept the original Norwegian surname of Erfjord which was the name of the city/town in Norway that they came from. Also Sven Erfjord.
