What's In A Name??

One's name is their identity. A name gives an individual relatability, particularly in literature. If the Duchess of Malfi was significant enough to score the title of the play, how is it that she couldn't manage to get an actual name? The Duchess has a title to be sure but her actual personal name is withheld from the text. I think that there is a significant reason for the Duchess not having a name. She is a powerful woman figure, not having a name makes her quite elusive. I also think that the Duchess's lack of a name secludes her from the audience, she is less personable. However, as I go on reading the play, I have come to find that she makes herself known to the audience, a contradiction to her secretive title.
