Also on Macbeth, have a look at AustenBlog's take on Lady MacDarcy:
The raven himself is hoarse
That croaks the fatal entrance of Lady Catherine
Under my battlements. Come, you shades of Pemberley
That tend on mortal thoughts, unsex me here,
And fill me from the crown to the toe top-full
Of direst cruelty!
Hee! There's more.
