Re: Carl Ericson and Esther Kjellin-Borlange
I checked my files, and I only had two that may have had a Chicago link.
First one Knut Ericson, 32 yr. old male, residence Chicago.Sailed Lusitania June 12, 1908.Line 15 on manifest.He is listed as a US citizen.
Second: Knut Ericson, sailed Bergensfjord on Aug 1, 1923.Went to visit his brother Carl Ericson, but in Minnesota.There were other Ericsons on that ship, but it looked like they were going to MN.Check out lines 25-30 of that manifest.
I don't know if any of this helps, because I don't know the ages of your relatives.Good Luck! :)
