However, the 74-year-old count reunited with his estranged wife, Agnes of Guelders, and fathered a daughter, Ermesinde, who displaced Baldwin as heir presumptive.

[3] When Theobald died in 1214, Ermesinde married Count Waleran III of Limburg (1180–1226), with whom she then ruled Luxembourg.

She proved to be an effective administrator, granting charters of freedom to several towns and increasing the prosperity of her country.

In 1747, shortly before the old abbey was destroyed by French troops, the nuns had hidden Ermesinde's remains in a chapel, where they were found by the Jesuits during 1875-1877 reconstructions.
