History is full of secrets-lost heirs, forgotten soldiers, mysterious photographs, and lives that vanished without a trace. The Unknown Dead takes readers inside the extraordinary world of genealogical sleuthing, where historical research, DNA analysis, and detective work converge to uncover hidden truths. From a soldier who disappeared twice, to a phantom twin revealed through DNA, to immigrants whose names never appeared on arrival records, each chapter explores real-life mysteries solved through meticulous family research. These stories read like true crime, but instead of crime scenes and police reports, the detectives follow census records, ship manifests, probate files, letters, and heirlooms to restore identities lost to time.Part detective story, part historical exploration, and deeply human, this book reveals how genealogists piece together fragments of the past to solve mysteries that span generations. For anyone fascinated by history, family, or the thrill of discovery,
