Hi Norwayheritage!! My Great-Great Grandmother Eli Kristiansd Delviken (b. 1837) went to America (Marinette, Wisconsin ?) 1880 with her two sons Kristian and Olaf. Ship: Angelo See 25089, 25090, 25091 here http://www.digitalarkivet.no/cgi-win/webcens.exe?slag=visbase&sidenr=24&filnamn=emikra1&gardpostnr=25089&personpostnr=25089#nedre Is it possible to find out something about them in America? The only info I have is that Eli may have married a guy from Sweden... Jan, (Mr.) Norway
