Numberings and names can vary and the year details have several uncertainties and should be taken as approximative due to some conjecture in lack of complete documentation. In this list mostly the English name versions are used.
Gerhard I, Count of
Clervaux (1129-1156), son of Gerhard.
Frederic I of Vianden [
de] (1124-c. 1150), son of Gerhard. According to some accounts Frederic I was appointed as the "first count of Vianden", as a
Vogt of
Prüm and Undervogt of
Electorate of Trier. Probably married to a daughter of Bertolph.
Frederic II of Vianden [
de] (1163-1187), son of Frederic I. Married countess Elisabeth of
Salm, and became count of Niedersalm (1163-1175) jure uxoris, while Elizabeth's brother Henry II got Obersalm. Their son William I inherited the county of Niedersalm.
Frederic III of Vianden [
de] (1184-1220), son of Frederic II. He married Mechthild (Mathilde), assumingly of
Neuerburg, with a disputed and confusing ancestry. At least their son Frederic I inherited Neuerburg, and married Cecilie of Isenburg Kovern, but that dynasty became extinct with the death of Frederick III in 1332.
