She graduated in 1961 from Mankato High School. In 1965, she earned her B.A. and teaching certificate from Macalester College in St. Paul, and taught elementary school after college. She was united in marriage to Lyle G. Jacobson on June 19, 1965, at the First Presbyterian Church of Mankato. For the next 13 years, Kay and Lyle made their home in Rochester, MN, raising three children, Amy, Lori and Eric. In 1978, the family moved back to Kay's hometown of Mankato, where Lyle joined Katolight Corporation (now Rolls-Royce Power Systems). Katolight was a family business co-owned by Kay and her sister, Marcia Richards. Kay and Lyle became sole owners in 2002, and sold the company in 2007. Kay belonged to the Presbyterian churches in both Rochester and Mankato. She was a member of Chapter DA P.E.O. Both Kay and Lyle, happily married for 55 years, were active and generous supporters of many Mankato initiatives, including the Children's Museum of Southern Minnesota, the Mankato Area Foundation, Habitat for Humanity, the Mankato Symphony Auxiliary, and beautification efforts for downtown Mankato. Kay enjoyed summers growing up on Lake Washington, and returned to live on the lake from 1998-2021. She inspired many over the years with her beautiful gardens. Kay enjoyed numerous world-travel adventures with Lyle and their close friends, as well as entertaining and hosting cousins and extended family for holiday gatherings. She appreciated spending time with her children and grandchildren at her Lake Washington home, as well as at Ruttger's Bay Lake Lodge in Deerwood, MN., and at her and Lyle's winter home in La Quinta, CA.
