1880 Trail, Dakota Territory
L. G. Ohman, b. Sweden, 43, farmer
Johanna, b. Sweden, 42

Lars Gustaf Ohman
Born: June 5, 1837, Uppsale Kommun, Uppsale Ian, Sweden
Died: Feb 5, 1917, Lake Park, Becker, MN

I didn't find any of them in a census subsequent to the 1880 Census.
Amanda could have married in Trail or Becker County, MN.
I'd contact the Lake Park Area Historical Society
C/O Carol Midthune
PO Box 193
Lake Park 56554-0045
and ask if they can provide a copy of Lars obituary. If not, they might know who to contact.
You'll find Becker County Cemetery info at www.mngs.org/becker.htm
The Becker County Historical Society & Museum, www.mnhistoricnw.org/museums/becker-county/
might be able to provide more info about them. Successful Searching!
