I learned several things: 1. Their last name when they left Norway was Erlandsen and that they came from the town of Vinger, which is near Kongsvinger in eastern Norway. I found only a few Erlandsen's and almost no Ellingsons. This site could be helpful to other's trying to find when their Ellingson's/Erlandsen's arrived in this country.
Karelius Erlandsen, wife Marthe, and three children sailed from Oslo on April 5, 1889, bound for Ridgeway, Iowa. It's exciting to actually get back across the water!
