LONGUEVILLE, the name of a French family which originated with Jean, count of Dunois, the “Bastard of Orleans,” to whom Charles VII. gave the countship of Longueville in Normandy in 1443. François of Orleans, count of Longueville, was created duke in 1505. The marriage of his brother Louis with Jeanne, daughter and heiress of Philip, count of Baden-Hochberg-Sausenberg (d. 1503), added considerable estates to the house of Longueville. Henry, duc de Longueville (d. 1663), took an important part in the Fronde, and for a long time held the royal troops in check in Normandy. His wife, Anne Geneviève (see below), was a leading figure in the political dissensions of the time. The last of the family was Jean Louis, the Abbé d’Orléans, who died in 1694. The numismatist, Charles d’Orléans-Rothelin (1691–1744), belonged to a bastard branch of the family.
