Who married Henry II, Count of Nassau?

Henry II "the Rich" of Nassau (German: Heinrich II. "der Reiche" von Nassau; c. 1180 – 26 April 1247/48/49/50, before 25 January 1251) was Count of Nassau. He distinguished himself in particular by his chivalrous and devout spirit. He was charitable and made great donations to the church, so that the monasteries and prayer houses in the area of present-day Nassau experienced the most significant bloom in his time. The greatest favour was the Teutonic Order to enjoy, to which he donated especially for the renunciation of his brother's, upon his entry into the order. Henry participated in the Sixth Crusade. He was the builder of the castles Sonnenberg, Ginsburg and Dillenburg.

Machteld van Gelre en Zutphen († 28 oktober, 1247 of later), ook Mechteld of Mechtild(is) genoemd, was een gravin uit het Huis Wassenberg en door huwelijk gravin van Nassau. Ze is een directe voorouder van zowel de koningen van Nederland als de groothertogen van Luxemburg.
