History, in the end, is only another kind of story, and stories are different from the truth. The truth is messy and chaotic and all over the place. Often it just doesn’t make sense. Stories make things make sense, but the way they do that is to leave out anything that doesn’t fit. And often that is quite a lot.
Stories which have failed either to become popular folk lore or to be embalmed in old newspaper files are in great danger of oblivion. If they are saved, often it is by the merest chance. And that chance may well depend upon one individual with a treasure-story bent and a retentive memory.
