  Marriage Notes:

In March 1265, Isabelle married Guy of Dampierre.[1] Her marriage was determined by events that occurred many years before her birth. Indeed, around 1165, her great-grandfather Henry IV the Blind, Count of Namur and Luxembourg, had no children from his first marriage. He named his brother Baldwin IV of Hainaut as his successor. Baldwin died in 1171, and Henry the Blind confirmed his nephew Baldwin V of Hainaut. But with one more attempt to have children, Henry the blind married his second wife Agnes of Gelderland. Agnes bore a daughter, Ermesinde and thus had broken the promise he had made to Baldwin. A war however ensued, with the result that Baldwin would be Henry's designated heir in Namur.

Isabelle's father claimed his rights of Namur, being son of Ermesinde. Henry V failed on his claim to rule Namur. Isabelle's parents wanted to make peace with Guy over a dispute of Namur. Isabelle became Guy's second wife; his first wife, Matilda had died one year earlier. Guy already had eight children with Matilda. Isabelle gave-birth to another eight children:
