DAUVERGNE (CLAIRE), daughter of the preceding and sister of Sophie.  The two sisters were both charming blondes, one eighteen and the other twenty, who, amidst a constant stream of gaiety, looked after the housekeeping with the six thousand francs earned by the two men.  The elder one would be heard laughing, while the younger sang, and a cage full of exotic birds rivalled one another in roulades.  La Bete Humaine.

DAUVERGNE (HENRI), a chief guard in the service of the Western Railway Company.  He was in love with Severine Roubaud, but was aware of her liaison with Jacques Lantier.  He was injured in the railway accident at Croix-de-Maufras, and having been removed to a house which belonged to Severine, he was nursed by her there.  In a hallucination of illness, he believed that he heard, outside his window, Roubaud arranging with Cabuche for the murder of Severine:  his mistaken evidence was greatly instrumental in leading to the conviction of the two men.  La Bete Humaine.

DAUVERGNE (SOPHIE), the elder of the two sisters.  La Bete Humaine.

DAVOINE, the purchaser of Chanteau’s timber business at Caen.  When Chanteau became incapacitated by gout, he sold his business to Davoine for a hundred thousand francs, of which one-half was to be paid in cash and the balance to remain in the business.  Davoine was, however, constantly launching into speculations, and the consequence was that the profits were drained away, and the balance sheet generally showed a loss.  He ultimately became bankrupt, and Chanteau lost all the money he had left in the business.  La Joie de Vivre.

DEBERLE (DOCTOR HENRI), a medical man of Passy who inherited from his father a large fortune and an excellent practice.  A chance call to attend Jeanne Grandjean led to an intimacy with her mother, which resulted in the fleeting love episode which forms the subject of the novel.  Deberle, deceived by the circumstances under which Helene Grandjean prevented an assignation between his wife and M. Malignon, believed that Helene had arranged an assignation with himself, and she found it impossible to enlighten him without compromising his wife.  The brief liaison was terminated by the illness and death of Jeanne.  Une Page d’Amour.

DEBERLE (MADAME JULIETTE), wife of the preceding, was the elder daughter of M. Letellier, a wealthy silk merchant of Paris.  Empty-headed and fond of gaiety, she was carried away by the attentions of M. Malignon, an idle young man who went everywhere in Paris society, and to whom she was foolish enough on one occasion to grant an assignation.  Madame Helene Grandjean, who was on intimate terms with the family, warned Madame Deberle that her husband’s suspicions had been aroused, and that lady, seeing in time the folly of her action, broke off the intrigue.  Une Page d’Amour.

DEBERLE (LUCIEN), the young son of Doctor Deberle.  He was a playmate of Jeanne Grandjean.  Une Page d’Amour.
