Tonette Modahl

Seeking information on my husband's grandma "Nettie" Modahl Olson. She married Carl Arthur Olson. Tonette is buried in Minnesota at Lakeview Cemtery wth otehr siblings, but I cannot locate what farm she came from, etc. She had many friends who would fly over around 1972-73 from Norway to the farm in Antelope Montana for visits, my husband recalls. The Amercian actress Arlene Dahl apparently is his cousin, but she rumor is that she dropped the "Mo" from her name when she became famous.....
