That same year she established the first of many, "Heartsease" in Saybrook, Connecticut for "tired women, girls and children." As such, Morgan can be considered part of the Deaconess movement in which over 5000 Protestant women participated circa 1890. In 1901, Morgan purchased what became their headquarters and retreat center, in Byfield, Massachusetts, which was named "Adelynrood" upon its renovation in 1915 (remembering both Howard, who had died in 1898, and an old word for "cross"). Another home with daily religious services attended by Protestants, Jews and Catholics, was called "Beulahland". In 1906, Morgan bought the Putnam Elms, the Windham County, Connecticut home of Morgan's maternal great grandfather Colonel Daniel Putnam from 1791 until his death in 1831. She also helped found the Colonel Daniel Putnam Association in 1910. In her later years, Morgan led a Sunday School class at Trinity Church, Boston. Emily Malbone Morgan was buried in Hartford's Spring Grove Cemetery. The Episcopal Church (USA) remembers her liturgically on February 26. Her cousin, Daniel Putnam Brinley (1879-1963), became a well-known muralist, as well as a leading Episcopalian, and her biographer Vida Dutton Scudder is also honored on the Episcopal liturgical calendar (on October 10). The Society of the Companions of the Holy Cross currently has approximately eight hundred members and continues to operate retreat centers.
