Lady Caulfield is an unseen character mentioned in the fifth season.
Lady Caulfield is the head of House Caulfield.
In the booksEdit
In the A Song of Ice and Fire novels, there is no mention of any House Caulfield. The mention of "Lady Caulfield" in the TV show is apparently an in-joke reference to one of the TV show's producers, Bernadette Caulfield.
