I'm a Norwegian Genealogist looking for "the needle in the haystack":
Olena Plante b. ab. 1902, Rolette, N.Dakota.
Married Louis Tennancour early20's.
Got the children Donald, "Boyd" and Lorraine??
Moved to Misoula, Montana, then I "lost" them.
Some few days ago I got info saying they might have moved on to Idaho Falls where Olena Tennancour died May 1979.
Her obituary may contain interesting information for me.
