Well, many of the 1897 characters are very Victorian. I suppose Rachel is fairly Dickensenian, even if the chief of the plot was lifted from Jane Eyre.
I really don't see much of a resemblance between Madame Defarge and Danielle Roget. The former was driven by revenge, whereas the implication for the latter is that she was just having a grand old time with the Revolution.
I don't know how much of a Dickens thing DS had going. The Bronte sisters' writing seems closer to the spirit of DS.
