Searching for Elizabeth Everson

I've tried for months to locate great grandfather Everson. Didn't have his first name. However Martin Everson my grandfather shows on his death certificate in Fargo ND 1923 it states "father unknown" It does show mother as Elizabeth Everson. It never accured to me that was her maided name and she was never married and so My grandfather Martin wouldn't know who his father was. My grandfathers death certificate list him born in Odalen Norway in 1875. Which if I was lucky enough that would be where his mother was from. If anyone out there has an Everson Line or are looking for an Everson it would be great. Sweetbarb[:)]
