This collection contains correspondence between brothers Raymond Taylor and Samuel W. Taylor between 1966 and 1972. Their correspondence concerns research and work surrounding the publication of Samuel's The Kingdom or Nothing: The Life of John Taylor, Militant Mormon (see full citation below). Both brothers were highly involved in researching John Taylor, their grandfather, for this book and Samuel credits his brother Raymond for an ample share of the work toward its research and publication. The correspondence in this collection was originally bound in a binder by Raymond Taylor and the organization of the collection reflects this original order.
