Adelheid of Katzenelnbogen

She is a direct ancestor of the Walramiam branch of the House of Nassau and of the Grand Dukes of Luxembourg.

On 16 December 1255, her spouse divided the county of Nassau with his younger brother Otto I, on which occasion Walram obtained the area south of the river Lahn, containing Wiesbaden, Idstein, Weilburg and Bleidenstadt.

[2] From this union came the following children:[1][3] Walram died – allegedly in mental derangement – on 24 January 1276.

As a widow, Adelheid was a Clarissan nun in Wiesbaden (in the summer) and in Mainz (in the winter).

The necrology of the St. Clara monastery in Mainz recorded the death of ‘Alheidis … comitissa de Nassowe’ on ‘Non Kal Mar’ in 1288, and her burial ‘in habitu soror’.
