On March 15, 1923 she married Morris Otto Evanson (1893-1975). The couple had no children.

With the coming of television in the late 1940s she expanded in her career appearing on such shows as You Are There, The Loretta Young Show, Chevron Hall of Stars, Jane Wyman Presents The Fireside Theatre, The Millionaire, Zane Grey Theater, Alfred Hitchcock Presents, The Frank Sinatra Show, Bachelor Father, Alcoa Presents: One Step Beyond, and Lassie.

A stage Actress as well as film star, Evanson often appeared in productions which were staged in the Los Angeles area. She played a Swedish mother reminiscing about the births, deaths, and lives of her children in DeWitt Bodeen's play, Harvest of Years in 1946 (Evanson's performance was called "poignant" by the Los Angeles Times). Although Evanson had played one of the aunts in the 1948 film I Remember Mama, she portrayed Mama herself on stage just a year later.

In the late 1960s and early 1970s Evanson found herself getting little work in Hollywood due to her advancing age; in 1974 she made her last appearance in an episode of Apple's Way.

Evanson was a lifelong member of the Democratic party. Following her retirement, she lived in Riverside County, California, until her death from heart failure on November 29, 1980. Her ashes were scattered into the Pacific Ocean.
