Jean DE DAMPIERRE

   Research Notes:

The Genealogica Comitum Flandriæ Bertiniana names (in order) "Guillelmum Guodnem et Iohannem" as the three sons of "Guillelmo domino de Dampetra [et] Margaretæ", specifying that "primo mortuo sine liberis in tornramento apud Trasegnies". Matthew of Paris specifies that his parents had "two others" when he records the parentage of his brother Guillaume, but does not name the other children. The Annales Blandinienses name "Iohann de Dampetra" as brother of Guy Count of Flanders, when recording the liberation of the two brothers from captivity in Holland.

Seigneur de Dampierre-sur-l'Aube, de Sompuis et de Saint-Dizier. Vicomte de Troyes. Connétable de Champagne.

He was captured at the battle of West-Capelle 4 Jul 1253 by his half-brother Jean d'Avesnes Comte de Hainaut, released in early 1257. In Jun 1256 he recognised that the officer of Connétable de Champagne was not hereditary.
