Mary, Countess of Blois

Mary of Avesnes (1226-1241 witnessed ) was from 1231 Countess of Blois and Dunois (formerly Châteaudun ).

Parents

She was the heiress of her parents Walter II of Avesnes and Margaret of Blois. From her mother she inherited after her death in 1230, and Mary the counties of Blois and Châteaudun, the latter county Dunois was called from now on. Your office meant not only the end of the house Blois in the Loire Valley, but also the end of the political importance of the county of Blois in France. She herself played no role in French politics. About her father she had hereditary claims on its dominions Avesnes, Guise, Condé, Leuze, Landrecies and Trélon. However, since they died before their father, this was ultimately succeeded by Mary 's eldest son, John.

Marriage and issue

They married in April 1226 Hugo I of Châtillon († April 9, 1248 ), who became the Count of Blois by this marriage. 1240 he inherited the county of Saint- Pol. Their children were:

Counts of Blois Margaret, Countess of Blois Avesnes-sur-Helpe Leuze (Aisne) Counts of Saint-Pol Guy III, Count of Saint-Pol Ancre Aubigny-en-Artois Henry II, Duke of Brabant Robert I, Count of Artois List of counts of Artois Troissy Marigny
