A family of the duke's ministeriales of the upper Mur valley, named after the castle of Liechtenstein above Judenburg, which Dietmar I built before 1140.
In the thirteenth century their domain centred on Murau (the Liechtenstein court of law on the Mur is first named in 1256, Murau itself in 1250) and the poet Ulrich built the Frauenburg near Unzmarkt; none of that is pinned for 1200. On 1 January 1200 they are a ministerial family round Judenburg. Not to be confused with the Austrian Liechtenstein of Petronell and Rohrau (Liechtenstein).

Where the sources disagree
- The brief names 'Liechtenstein (Murau)': Murau is first named in 1250 and the Liechtenstein court at Murau in 1256, so the family's Murau lordship is not shown for 1 January 1200.
Evidence: The genealogy in the poet's article is not a charter list; the castle's location is approximate here.
On the map: A disc round the castle; position approximate.
