Samuel Roskelley (1837-1914) was an English convert to Mormonism in the 1850s. He emigrated to Utah and spent the rest of his life in Cache Valley, Utah, though making two missionary journeys back to Britain. This volume provides textual reproductions of his manuscript diaries, documenting his two missionary efforts in southern Wales and London, the complexities of farming, polygamy, and church service in the late nineteenth century.
