Choose an organizing rule
A family history book can move by generation, by couple, or by one person's life. Pick one rule and use it consistently. Memories Book uses the family tree and person sections to give the reader a repeatable structure.
A branch book often begins with the starting person, then moves through parents and earlier generations. A single-ancestor book can spend more space on that person's own photographs and stories.
Give every section enough context
Use a full name, lifespan, and family relationship near the start. Then place photographs, written memories, and documents with that person. Captions should say who, where, or when when the information is known.
Do not fill gaps with guesses. If a date is uncertain, keep the uncertainty visible in FamilySearch before building the book.
Write stories in a human voice
A useful family story states what happened, who was present, and how the teller knows. Preserve distinctive phrases when a relative's wording carries the memory. Cut repeated background that already appears elsewhere in the section.
Short stories are welcome. A paragraph about a habit, a job, a house, or a family trip can explain a photograph better than a broad life summary.
Edit for the reader, not for total coverage
Check whether the same event appears in several memories. Keep the strongest account and useful supporting documents. A focused book can link relatives to the larger FamilySearch tree without reproducing every item in one volume.
