The Corays' first residence in Utah was a house adjacent to the
Salt Lake Theatre. Then, in 1855, the family moved to
Tooele, Utah, where Coray oversaw dairy production on their farm. Unsatisfied with life in Tooele, the Corays relocated, splitting their time between a house in
Provo and a farm in
Mona. With this move, Coray shifted her home industry focus from producing cheese to crafting soap and distilling ointments. Her soap production served as the family's contribution to the
United Order, an initiative pushing towards Latter-day Saint self-sufficiency. Financial difficulties often plagued the Coray family, and, during times of famine, Martha Coray would feed her children watercress, lilies, rabbit meat, and wild onions. She would also make candles of
tallow, which the children would then sell to the community. Over the years, her role oscillated between frontierswoman and middle-class wife as the family's financial situation shifted. Coray stepped in to assist Howard financially whenever needed. Though she never received formal schooling herself, she taught school multiple times throughout her life. While her husband, Howard, was serving as a
Latter-day Saint missionary, Coray stood in for him in his teaching position at the University of Deseret (now the
University of Utah). She also taught Sunday School and served on the local
LDS Sunday School Board. Her son George went on to attend
Cornell University and later became a professor at the University of Utah, and her daughter Martha Jane Coray Lewis became a writer. Towards the end of her life, her grown children moved to Mona to build homes for their own families on the Coray property and live there.
Law and politics Once her children were grown and more free time became available to her, Coray became involved in Utah politics. Her priority was helping the Latter-day Saints maintain their autonomy in Utah Territory, and she contributed to this effort by producing homemade liniments and health products, as well as establishing a Latter-day Saint-operated school; financial support for educational institutions in Utah Territory at the time was not well-established or stable. Coray had her own income, voted in local elections, and owned land. Because the Salt Lake City Land Office required that landowners live on their property, the Corays transferred their Provo home to Martha's name in order to maintain both that property and their farm in Mona. Coray also worked as the representative for the ''
Woman's Exponent,'' an LDS woman's publication, in
Nephi and Mona; she sold subscriptions and subscribed herself. In addition to the histories she recorded throughout her life, Coray wrote pieces on women's rights, and some of her writing was published in the
Exponent. Coray also took an interest in law. On multiple occasions, she inquired after patenting some of her homemade products and production methods. She also advised friends and neighbors on legal matters, often holding power of attorney for them and appearing in court. She took charge of legal matters for the irrigation efforts in
Juab County, Utah, which became the Mona Irrigation District. Coray never attended law school or received formal legal training of any kind, but her participation in legal matters regardless was in line with convention in Utah at the time. Her legal knowledge came in handy when family members endeavored to start businesses or purchase land. Her daughter Martha described her as "a rapid and lucid writer, a brilliant conversationalist, and a fine speaker on a wide range of subjects," including history, philosophy, poetry, and law. ==Brigham Young Academy==
