Adolf Hitler est né le 20 avril 1889 à Braunau am Inn, Upper Austria, Austria-Hungary [aujourd'hui Austria]. Il était marié à Eva Braun. Il est mort le 30 avril 1945 en Allemagne.
William Patrick Hitler, son of Adolph's half-brother Alois Hitler, fathered four sons. One son died in an auto accident in 1989. Another son has described his ancestry as "a pain in the ass." William Patrick's three surviving sons are the only living descendants of Hitler's paternal line of the family and are, quite literally, the last of the Hitlers.
