Here is a copy of the marriage certificate for the second marriage of Ole and Mari Finnestad's great grandson, Orville Ilin Olson. Orville and Margaret (Carlson) married on June 21, 1949 in Chehalis, Lewis County, Washington.
Orville was the son of Mary (Knutson) and Stephen Olson and the grandson of Elizabeth (Finnestad) and Ole Andreas Knutson.
The marriage certificate indicates Orville was divorced, however, his first wife, Ida (Govig) had died February 7, 1923 in McIntosh, Polk County, Minnesota.
Neither the 1930 US Census or his World War II draft registration indicated he had remarried and I haven't stumbled upon any other information that would indicate Orville had remarried between 1923 and 1949.
