Lillian A. Root (b. Hall) (1851-1934) was born in Monroe County, Michigan, and died in Denver, Colorado. She took the surname of her stepfather, Blatchley, after her mother remarried in 1859, and moved with her family to San Francisco, California, around 1860. She married Edwin C. Root, a deputy county clerk, in San Leandro, California, in 1870. Sometime prior to 1880 they moved to Denver, and Edwin became the Superintendent of Mines for the State of Colorado. Root was healed through Christian Science treatment in early 1886, studied Christian Science with Minnie B. Hall De Soto, a student of Mary Baker Eddy's, soon thereafter, and began working as a Christian Science practitioner. Root wrote to Eddy in October 1886 to inquire about taking the Normal and Obstetrics classes with her, but there is no record of her subsequently doing so.
