I asked this question back a few weeks ago, about chapter 35: did Georgiana actually have her own home, or flat, or rooms, as I think is indicated in the text by the use of the word "establishment." Here is the url, but this is essentially my question found there:

I got several answers then, which I had also considered, but JulieW said there is a sentence at the end of the book which answers my question. I haven't recognized it; sorry Julie! The only thing I found which has a bearing on it is: "Pemberley was now Georgiana's home" from chapter 61.
