Johannes Olsen Korum was actually born in Feb 1854 and sailed for America (St. Paul) in 1881 as a single man. He ended up in Douglas Co. MN sometime about 1883 or 1884. His mother's name was Johanne and Arne (Olsen) Korum was his older brother. He also had a younger brother by the name of Johan.
I believe he is the father of Josephine/Josephina/Josie Korum (born 1886) but she was born in Minnesota. Also by the time of the 1910 federal census he is listed as having been married more than once.
I believe the family is confused about where Josephine was born.
We cannot do good research to help this family get started without knowing more about Josephine. For example, did Josephine's family actually ever live in Douglas Co. Minnesota? Where is 'Jamestown' as the poster has stated she died? What name was she known by when she died? using a husband's name? The family will have to check basic facts before more could be done.
