Looking for info on Anna Martha Johnson

I do not know if this site will help or if you guys do this kind of stuff. My G+g+grandmother was Anna Martha Johnson Svenson. She was born on July 13, 1860 In Ojgord Koppervik Norway. I think her parents may have been Margaret and John Johnson. She should have been traveling with her daughter, Amelia Selena. I cannot seem to find her in the emmigration records. I know she came to the U.S. because she married my great great grandfather in 1889. The daughter was born in norway in 1882. Her first husband possibly Benjamin? Johnson supposedly died at sea on a fishing vessel. ANY information would be MOST helpful. Thanks. Erica
