Whitney prepared a biography of Lorenzo Snow, a member of the Quorum of the Twelve, for publication in 1890. However it was not published at that time. It was entitled, "Latter Leaves in the Life of Lorenzo Snow". In 2012, Dennis B. Horne published an edited and expanded version of this work under the same title with Cedar Fort, Inc., of Springville, Utah. This work covered the Snow's life from 1885 to 1889 and was written as a continuation of Snow's sister Eliza R. Snow Smith's work "Biography and Family Record of Lorenzo Snow". In publishing this work, Horne included Whitney's work as the first nine chapters of his book and then covered the following 11 years of Snow's life. Horne's published record only included about a third of Whitney's manuscript of his history of Lorenzo Snow.
