"Nicholas was married to Matilda de la Roche, the widow of Thierry de Walcourt. She was the daughter of Henry I of la Roche (c. 1100 – 1126), Count of la Roche and warden of Stavelot and Malmedy and his wife, Matilda of Limburg. Her paternal grandfather was Albert III, Count of Namur; her maternal grandfather was Henry, Duke of Lower Lorraine. "

"By early 1153 he had inherited the lordship of La Roche-en-Ardenne from another cousin on his father's side, Henry II of La Roche. "
Dat klinkt alsof niet Hendrik I "de Blinde" van Namen haar vaders is, maar dat zij een zuster is van Henry II van La Roche, en zoon van Henry I van La Roche (1100-1126).
