There was another short letter enclosed purporting to be from his mother to his prior caretaker. It stated that his name was Kaspar, that he was born on 30 April 1812 and that his father, a cavalryman of the 6th regiment, was dead. In fact this letter was found to have been written by the same hand as the other one (whose line "he writes my handwriting exactly as I do" led later analysts to assume that Kaspar himself wrote both of them).
