Mims married
Sue Harper, a native of
Brandon, Mississippi, in 1866. Mrs. Mims developed a serious incurable illness that lasted 15 years until in early 1886 Sue Harper Mims was healed through
Christian Science. She later became a Christian Science Practitioner and later a Teacher of Christian Science. Mrs. Mims also became a lecturer of Christian Science, traveling around the United States giving talks on Christian Science and
Mary Baker Eddy, the Discover and Founder of Christian Science. She was instrumental in the development of Christian Science in Atlanta, Georgia, ultimately hosting church services in her home before the first Christian Science church in Atlanta was built. Regarding his own religion, Livingston Mims said: :"I do not know exactly the church to which I owe allegiance, as I am a contributor to several. My wife is a Christian Scientist, my daughter is an Episcopalian, my father was a Baptist, my mother was a Presbyterian, and I am a confederate Veteran with inclinations to the Salvation Army." ==Legacy==
