Marie de Dampierre-Bourbon, was a Lady of high lineage from the families of Dampierre and Bourbon. By her marriage, she entered the family of the counts of Dreux, cadet branch of the Royal Capetian House.
Marie was the daughter of Beatrice de Montluçon and Archambaud VIII de Bourbon-Dampierre (aka Archambaud le Grand), heir to the lordship of Bourbon by his mother Mathilde de Bourbon. Archambaud VIII of Bourbon, held in possession that is now "de Bourbon-Dampierre", the lordship will be held by women twice(by extinction of the males) and will lead to the Bourbon line that will have access to the throne of France.
Marie married in 1240 John I of Dreux (1215-d. 1249), fourth count of Dreux and Braine. She thereby enters the Capetian family, a more ancient Royal House of France and Europe, the counts of Dreux being from Robert I, son of the King of France Louis VI le Gros.
From this marriage were born:
Robert IV (1241-d. 1282), 5th count of Dreux and of Montfort.
Yolande (1243-d. ap.1304), Countess of Braine, married firstly Amaury II († 1269), Lord of Craon, and then to Jean de Trie (died 1304), count of Dammartin
John (1245-d. ap.1275), Templar.
Marie died in 1274 and her body was buried in Abbey Church Saint-Yved de Braine, her internal organs, heart and entrails are entombed at the "Collegiale de Saint Etienne de Dreux".

"Icy gist le cœur de Marie,
Cœur et prudent et généreux,
Que J.-C. chacun l'en prie,
La comble de présents aux cieux;
Sans cesse elle en fit de pieux.
Si l'on se conservoit la vie,
Par bel esprit, biens et vertu,
Marie eust a jamais vescu;
Puisque hélas! la mort l'a ravie,
Grave en ton triste souvenir
La nécessité de mourir."

"Here lies Mary's heart,
Thoughtful, wise and generous,
May Jesus Christ, all do pray,
Help her to join those already in Heaven;
Ceaselessly, she remained pious.
And if one could preserve a life,
By wit, goods and virtue,
Marie to survive in eternity;
But alas! Death arrived to her delight,
Gravest of the sad memories of her loss
Is the very need to die."
