Ann Mary Jarvis (c.1833-?) was born in Warren, Maine, and died in an unknown location. In the 1850s, her family was stricken with tuberculosis. Jarvis' parents and many of her siblings passed away over the decade and she was granted guardianship of her younger siblings, Hannah E. Jarvis and Joseph R. Jarvis, in October 1862. Jarvis was a patient of Phineas Parkhurst Quimby. Mary Baker Eddy met Jarvis, whom Eddy called "Mary," during one of her visits to Quimby in Portland, Maine, in 1864. Jarvis' sister Hannah passed away in early February 1864. That March, Eddy stayed with Jarvis in her home in Warren, Maine, for two months and used mental healing on Jarvis, who was ill. Eddy later described this healing in her book Science and Health with Key to the Scriptures. At some point after May 1864, Jarvis moved to Philadelphia, Pennsylvania. She married Stephen G. Holbrook, a tanner, in Boston, Massachusetts, in 1869.
