Hi Sue, I remember you posting this account years ago! But.. would Angus McIver not be able to confirm the name through reservation records? Would the newspapers not have wanted to put one of their ace traveling reporters on the case and bring this to ground quickly? Would Hauptmann not have talked about such a "once in a lifetime trip?" The account seems unlikely to me. Was there anything specifically you have seen that pointed to this being Hauptmann?
And speaking of buried treasure, wouldn't it be something if they found a telltale item such as a missing thumbguard buried beneath the ground on the former site of Hauptmann's garage?
