To write a family history, we must convert our ancestral information into paragraphs of prose. But how do we group the resulting paragraphs to produce a coherent structure? We start by asking ourselves what we wish to achieve. Are we writing a history that focuses on a surname line? Or one that covers all of our ancestors, or all of our descendants, or all of the ancestors and descendants of a particular person? And how do we craft an individual biography? Do we produce a family history that is a group of stand-alone biographies or one that has a narrative-style flow? These and other subjects are discussed in this simple guide to structuring a family history.
