Ole Martin Evensen 1882-1933

Ole Martin Evensen was born 3 Dec 1882 in Scandinavia, Waupaca, WI, and died 22 May 1933 in Milwaukie. Burial information: https://www.findagrave.com/memorial/75994275/ole-m_-evenson I am trying to find out more about his parents and where the family came from in Norway. I wonder if anyone has information. Ole's mother was Kari with names in various forms: Carrie, Karen/Karn/Carn. Kari was born in Norway 14 October 1845 and died in Scandinavia, Waupaca 14 April 1909, grave memorial https://www.findagrave.com/memorial/107945367/carn-bee Without a patronymic and/or farm name, it is difficult to search for Kari. Based on family information, I have searched Norwegian census and church records for Stange and also Vestre Slidre, but have not been able to find Kari in church records or to affirm that one of the 250 women named Kari in the 1865 census is our gal. Kari was apparently married twice, first to the father of Ole Martin Evensen, and then to a man named Barney/Bennie N. Bee. He was born in Norway, and I suspect that his original name could have been Bjarne Nilsen (?) Bøe. Kari and her first husband had another son who called himself Henry Evenson in the USA. He was born in Norway 18 May 1872 and died in 1957, grave memorial https://www.findagrave.com/memorial/137411936/henry-evenson Family members think that Kari's first husband and father of the two sons was a man named Christian Evensen, but I have not been able to find a likely candidate. The earliest US census information I have found is in 1900. Carrie, Barney and Ole were living in Waupaca. In Kari's will the name the name "Engen" is inserted after Ole M Evenson. This may have been a farm name in Ole's father's family, but this is the only reference I have found.

In the 1930 census they were living at 144 Seeley Street in Milwaukee. Ole apparently converted to Catholocism. Thanks in advance to any information or advice you all may have!
