A PDF of Isaac C. Wellcome’s 1874 publication History of the Second Advent Message and Mission, Doctrine and People. Wellcome was a member of the Advent Christian Church, the same denomination that George Stetson and Jonas Wendell belonged to. This is the part of Adventism that Storrs and Barbour were more allied with. There are several passages in Wellcome's book that refer to Storrs. Barbour gets a brief mention in the book.
Quoting from a review of the book: "Though primarily a historical narrative of the Millerite movement and an important source of information about early Adventism, Wellcome’s work also includes much theological discussion. His book, as historian Gary Land observes, is “a significant example of the Advent Christian side in the struggle to claim the mantle of William Miller.” Wellcome’s book records his own personal memories and those of others, includes biographical sketches of more than thirty-five Millerite and Advent Christian leaders, and provides quotations and lengthy extracts from other early published Advent materials, many of which no longer exist in original form."
