RupertRupert is only known by his Christian name, he probably never used a surname. He also probably never used a noble title equivalent to a surname either. The surname ‘of Laurenburg’ in the title of the article has only been added for technical reasons, and is derived from the surname of his son Dudo of Laurenburg. () was Vogt at Siegen and is one of the eldest known possible ancestors of the House of Nassau.

Life Rupert is mentioned at Siegen between 1079 and 1082 as the owner of parts of the lands of Lipporn/Laurenburg,Hesselfelt (1965). and in a charter from 1079/89 as Vogt at Siegen.Lück (1981), p. 16–17. He was a vassal of the Electorate of Mainz.Lück (1981), p. 16–17. Hesselfelt (1965): “Probably a vassal of the Electorate of Cologne”. It is possible that Rupert was already Count of Laurenburg, but he isn't mentioned as such in any charter.

Perhaps Rupert was a son of Adelhart, who is mentioned in a charter from 1048 as Vogt at Haiger for the Abbey of Worms. Rupert was the father of Dudo of Laurenburg.Lück (1981), p. 16–17. Hesselfelt (1965): “Probably the father of Dudo of Laurenburg”.

There are more persons known who, as owners of the lands of Lipporn/Laurenburg (and thus the predecessors of Rupert), probably also were his ancestors. The first is a certain Drutwin mentioned in 881 as a landowner in Prüm, and who is the oldest known possible ancestor of the House of Nassau.
