The quesion I have as to whether this woman was motivated by fear, by shame, or by a more practical consideration. If she was motivated by fear, i.e. she changed her idenity to hide from somebody in her previous life, it strikes me that this was a secret that sooner or later she would have shared with somebody such as, for example, a spouse. On the surface, it makes a lot more sense that she was motivated by shame, i.e. she didn't want people in her new life to know the details of her previous life. This is the kind of secret that one shares with absolutely nobody, and in this case, is literally taken to the grave. I know that is a relatively broad, simplistic categorization, but if she was trying to escape a religious cult, evade an abusive spouse, or hide from organized crime, she really didn't benefit at all by keeping that secret from people in her new life.
