CHATILLON  , the name of a

French family whose history has furnished material for a large volume in folio by A. du Chesne, a learned Frenchman, published in 1621 . But in spite of its merits this book presents a certain number of inaccurate statements, some of which it is important to notice . If, for instance, it be true that the Chatillons came from Chatillon-sur-Marne (Marne, arrondissement of Reims), it is now certain that, since the 11th century, this castle belonged to the count of Champagne, and that the head of the house of Chatillon was merely tenant in that place . One of them, however, Gaucher of Chatillon, lord of Crecy and afterwards constable of France, became in 1290 lord of Chatillon-sur-Marne by exchange, but since 1303 a new agreement allotted to him the countship of Porcien, while Chatillon reverted to the domain of the counts of Champagne . It may be well to mention also that, in consequence of a resemblance of their armorial bearings, du Chesne considered wrongly that the lords of Bazoches and those of Chateau-Porcien of the 12th and 13th centuries drew their descent from the house of Chatillon . The most important branches of the house of Chatillon were those of (I) St Pol, beginning with Gaucher III. of Chatillon, who became count of St Pol in right of his wife Isabelle in 1205, the last male of the line being Guy V . (d . 136o); (2) Blois, founded by the marriage of Hugh of Chatillon-St Pol (d . 1248) with Mary, daughter of Margaret of Blois (d . 1230),-this branch became extinct with the death of Guy II. in 1397; (3) Porcien, from 1303 to 1400, when Count John sold the countship to Louis, duke of Orleans; (4) Penthievre, by the marriage of Charles of Blois (d . 1364) with Jeanne (d . 1384), heiress of Guy, count of Penthievre (d .

1331), the male line becoming extinct in 1457 . See A. du Chesne, Histoire genealogique de la maison de Chastillonsur-Marne (1621) ; An; elme, Histoire genealogique de la maison royale de France, vi . 91-124 (1730) . (A . Lo.) CHATILLON-SUR-

SEINE, a town of eastern France, capital of an arrondissement in the department of Cote-d'Or, on the Eastern and Paris-Lyon railways, 67 m . N.N.W. of Dijon, between that city and Troyes . Pop . (1906) 4430 . It is situated on both banks of the upper Seine, which is swelled at its entrance to the town by the Douix, one of the most abundant springs in France . Chatillon is constructed on ample lines and rendered attractive by beautiful promenades . Some ruins on an eminence above it mark the site of a chateau of the dukes of Burgundy . Near by stands the church of St Vorle of the loth century, but with many additions of later date; it contains a sculptured Holy Sepulchre of the 16th century and a number of frescoes .

In a

fine park stands a modern chateau built by Marshal Marmont, duke of Ragusa, born at Chatillon in 1774 . It was burnt in 1871, and subsequently rebuilt . The town preserves several interesting old houses . Chatillon has a sub-prefecture, tribunals of first instance and of commerce, a school of agriculture and a communal college . Among its industries are brewing, iron-founding and the manufacture of mineral and other blacks . It has trade in wood, charcoal, lithographic and other stone . Chatillon anciently consisted of two parts, Chaumont, belonging to the duchy of Burgundy, and Bourg, ruled by the bishop of Langres; it did not coalesce into one town till the end of the 16th century . It was taken by the English in 136o and by Louis XI. in 1475, during his struggle with Charles the Bold . Chatillon was one of the first cities to adhere to the League, but suffered severely from the oppression of its garrisons and governors, and in 1595 made voluntary submission to Henry IV . In modern times it is associated with the abortive conference of 1814 between the representatives of Napoleon and the Allies .
