She is married to Otto II van Diessen.
They got married
Child(ren):
JUSTIZIA (-30 Jan ----, bur Thanning). The De Fundatoribus Monasterii Diessenses names "Iusticia cometissa" as wife of "Otto comes senior de Wolfratshausen" and in a later passage records her death "18 Kal Feb" and burial at "Danningen"[139]. The necrology of Diessen records the death "Feb III Kal" of "Justicia com, sepulta Daniggen, mater Hainrici Ratisponensis ep et Ottonis comitis fundatoris nostri"[140]. Her origin is open to some debate. Europäische Stammtafeln indicates Justizia as the daughter of Ernst Markgraf of Austria and his first wife[141], presumably based on Lechner[142], which would explain the transmission of the name Luitpold into the Wolfratshausen family. According to Wegener, she was the daughter of Luitpold, older brother of Markgraf Ernst, on the assumption that her father must be named Luitpold to justify the name transmission[143]. It is not certain that such an assumption is correct, and in any case the evidence for Luitpold having married is slim (see above). Hlawitschka, noting a family relationship recorded between Heinrich Bishop of Regensburg (Justizia’s son) and Leopold III Markgraf of Austria (the Historia Welforum which records “episcopus” [=Heinrich] referring during Lent to “cognatos et amicos suis” among which “marchione orientali Leopaldi seu aliis comitibus ac tocius Bawarie fortissimis” [assuming he was one of “cognatos” not “amicos”], dated to [8 Feb/25 Mar] 1133[144]), concludes that “die Herkunftsfamilie Justicias dürfte demnach feststehen”, but that “die genaue Filiation ist aber offen”[145]. m OTTO [II] Graf von Wolfratshausen, son of BERTHOLD [I] Graf von Diessen & his wife --- (-12 Apr [1122]). Graf von Diessen before 1107.]
