Web Notes notes for Simon DE DAMMARTIN Count Of Aumâle
Weis' "Ancestral Roots. . ." (109:29), (144:27). Cockayne's "Complete Peerage" (EU, p.167). Per Stuart's "Royalty For Commoners" (82:26), Count of Aumale, Ponthieu, & Montreul.
"Marie married, probably in 1210, Simon, younger son of Count Aubri II of Dammartin and Mahaut of Clermont. Simon became Count of Ponthieu and Montreuil *jure uxoris* according to the customs of that region. In 1214, however, he joined with his elder brother Count Renaud of Dammartin, Aumale and (*jure uxoris*) Boulogne in the conjuration of NW French nobles who backed King John of England against Philip Augustus of France--the group Philip smashingly defeated at Bouvines.
Marie reconciled with Philip a few years later, but only at the price of ceding to him a considerable amount of her inheritance; when Simon reconciled with the king, he agreed on pain of losing the entire inheritance not to marry his two eldest daughters (no sons survived at that time) without the king of France's consent.
