Mr. Wiffen, when compiling his elaborate _Historical Memoirs of the House of Russell, from the Time of the Norman Conquest_, had occasion to make some inquiries respecting a statement put forth by a M. Richard Seguin, a rich dealer in merceries and wooden shoes at Vire, in the department of Calvados; who, it appears, had a mania for appropriating the literary labours of others as his own, and, in fact, is stigmatised as a _voleur litteraire_ by M. Querard, in his curious work entitled _Les Supercheries Litteraires Devoilees_. Mr. Wiffen wished to ascertain M. Seguin's authority for affirming in some work, the name of which is not given by M. Querard, but which is probably the _Histoire du Pays d'Auge et des Eveques Comtes de Lisieux_, Vire, 1832, that the Du Rozels were descended from Bertrand de Briquebec. M. Seguin's reply is contained in the following letter from M. Le Normand of Vire, to whom Mr. Wiffen had written, requesting him to obtain M. Seguin's authority for his statement: "J'ai vu M. Seguin, et je lui ai demande d'ou provenaient les renseignements dont il s'etait servi pour dire dans son ouvrage que les Du Rozel descendaient des Bertrand de Bricquebec. _Il m'a repondu qu'il l'ignorait_; qu'il avait eu en sa possession une grande quantite de Copies de Chartres et d'anciens titres qui lui avaient fourni les materiaux de son histoire, _mais qu'il ne savait nullement d'ou elles provenaient_."--_Historical Memoirs, &c._, vol. i. p. 5. n. 1. The fact appears to be, that M. Seguin had obtained possession, through marriage, of a quantity of MSS., and was in the habit of printing them as his own works. Some of them had belonged to an Abbe Lefranc, one of the priests who were murdered in the diabolical massacre of the clergy in the prisons of Paris in September, 1792; and others of the MSS. had been the property of a M. Noel Deshayes, Cure de Compigni, whose _Memoires pour servir a l'Histoire des Eveques de Lisieux_, were published by Seguin as his own, but altered and disfigured under the title of-- "Histoire du Pays d'Auge et des Eveques Comtes de Lisieux, contenant des Notions sur l'Archeologie, les Droits, Coutumes, Franchises et Libertes du Bocage et de la Normandie; Vire, Adam, 1832."
