Lois was born March 26, 1928 to Jessie and Dewey Burns in Oklahoma. Her family then moved to Missouri before settling in California, where she graduated high school and soon met her husband Leo. They were married in 1949 and raised their family in Castella and in the redwoods of northern California. After raising their family, Lois and Leo moved to Montana, building a log house from the trees felled from their property. Lois was the center of her family, drawing in all her children and their families to her home every year on the 4th of July.
