It went to a cousin of the Duke who was murdered, he having no surviving children; but they say it went in the wrong line.

The cousin who had remained in France, and always managed to keep the favour of the ruling powers, got the title, and remade his fortunes; the others remained in England, very poor and very proud.

They would not have accepted any favours from the new royal family, but still they considered themselves deprived of their rights.
One of these Vandaleur _emigres_ (the one who ought to have been the Duke) had married his cousin.

They suffered great hardships in their escape, I fancy, and on the birth of their son, shortly after their arrival in England, the wife died.
There was an old woman, Aunt Theresa said, who used to be her nurse when she was a child, in London, who had lived, as a girl, in the wretched lodgings where these poor people were when they came over, and she used to tell her wonderful stories about them.

How, in her delirium (she was insane for some little time before her son was born), Madame de Vandaleur fancied herself in her old home, "with all her finery about her," as Nurse Brown used to say.
Nurse Brown seems to have had very little sympathy with nervous diseases.
