Mabel D. Davies (b. Woodruff) (1867-1963) was born in Bridgeton, New Jersey, and died in London, England. Her stepmother, Cecelia R. Woodruff (b. Read), was one of Julia Field-King's students, who in turn was one of Mary Baker Eddy's students. In 1892, Davies's stepmother and father, W. Harrison Woodruff, sent her to Boston, Massachusetts, to stay with Field-King and seek employment. While there she met Field-King's son, Clark D. Field, and they became engaged, but Field died unexpectedly in 1893 before the marriage took place. Nevertheless, Field-King referred to Davies as her daughter or daughter-in-law from then on. Davies joined The First Church of Christ, Scientist, in Boston, Massachusetts, on December 29, 1894. She and Field-King moved together to St. Louis, Missouri, and then, in 1896, to London, England. In both places the two were listed as practitioners under the same address in The Christian Science Journal. In 1899 Davies married Arthur P. Saunders Davies in Boston. He joined The First Church of Christ, Scientist, in Boston, Massachusetts, on June 3, 1899, and he took a class in Christian Science from Field-King. The couple settled in Pembrokeshire, Wales, where Davies's husband was from, and Field-King lived as a member of their household through at least 1902. Davies maintained her practitioner listing in the Journal until 1904.
