On December 14, 1944, she married William Morris Thomas, Jr. 1921-1977, in San Diego, California. Following the war, they both attended the University of California (Berkeley), graduating in 1948. For a short time, Bill worked with IBM in San Francisco, and Marjorie taught at Alameda High School. He and Marjorie owned one, then another, MG sports car. Their first son, Daniel Charles Thomas (1950-Living), was born October 8, 1950, in Alameda.
The family moved to San Diego in 1952, where Bill began working for the aerospace industry, while Marjorie continued her career in teaching, first with San Diego Unified Schools, and later with the Grossmont Union High School District, where she worked about thirty years, advancing from teaching into counseling and administration.
On September 16, 1958, Marjorie gave birth to their second child, Bruce William Thomas (1958-Living). By this time Bill had almost completed building a small sailing sloop, the Twod Oller, which was launched shortly thereafter in Mission Bay, and which he sailed in the early 1960s, until selling it. In the early 1970s, he and Marjorie bought another commercially constructed sailboat, the Santana, on which they made a number of cruises off the coast of Southern California and many weekend and day trips.
Following Bill's death in 1977 from pneumonia (complicated by cancer and alcoholism), Marjorie met up with a childhood friend, Herbert C. Kelly, Jr. They married in 1978. They celebrated their 23rd anniversary in May 2001.
