Dahlgren, Ole & Helena - Värmlands

[Eva-Lotta Dahlgren Andersson]

I seek information about my ggrandparents who imigrated to Minnesota from Värmlands in 1890:
 
Ole Dahlgren, born 26 JUL 1860
  married 2 DEC 1883 to
Helena , born 12 MAY 1855
 
I believe these children were born in Värmlands also:
John Dahlgren, born 5 DEC 1884
Axel Dahlgren, born 9 SEP 1886
Charlie Dahlgren, born 1 JUN 1888
 
I think they may have come from or near Likenäs or Dalby. Any information would be appreciated.
Thank you.
