Kind(er):
OTTO [II] von Diessen, son of BERTHOLD [I] Graf von Diessen & his wife --- (-24 Apr ----, bur [Diessen] St Stefan). Ellenhart Bishop of Freising “in manus Ottonis advocati” exchanged property, which was “ex beneficio Ottonis filii Perhtoldi co[mitis]” and with his consent, by charter dated 16 May 1060[1031]. Wegener identifies “Ottonis” as Otto Graf von Wolfratshausen[1032]. Graf von Thanning [1073]. Graf von Ambras 1078/1093. Graf von Wolfratshausen 1098/1116. Graf von Diessen 1100/1107. The De Fundatoribus Monasterii Diessenses records the death "VIII Kal Mai" of "Otto comes de Wolfraczhausen maior domus", specifying that he was buried "in…Sancti Stephani…iuxta fratrem suum"[1033]. The necrology of Diessen also records the death "Mar VIII Kal" of "Otto com senior et maior domus, sepultus ecclesia S Stephani, pater Ottonis fundatoris nostri"[1034].
m JUSTIZIA, daughter of --- (-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"[1035]. The necrology of Diessen records the death "Feb III Kal" of "Justicia com, sepulta Daniggen, mater Hainrici Ratisponensis ep et Ottonis comitis fundatoris nostri"[1036]. Her origin is open to some debate. Europäische Stammtafeln indicates Justizia as Justizia von Babenberg, daughter of Ernst Markgraf of Austria [Babenberg] & his first wife Adelheid von Wettin[1037], presumably based on Lechner[1038], 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[1039]. It is not certain that such an assumption is correct, and in any case the evidence for Luitpold having married is slim (see the document AUSTRIA). Hlawitschka, noting a family relationship recorded between Heinrich Bishop of Regensburg (Justizia’s son, see below) 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[1040]), concludes that “die Herkunftsfamilie Justicias dürfte demnach feststehen”, but that “die genaue Filiation ist aber offen”[1041].
Wegener suggests that Graf Otto [II] married secondly Adelheid, whom he supposes was the daughter of Heinrich [I] Burggraf von Regensburg, and that she was the mother of his children Otto, Heinrich, Adelheid and Elisabeth[1042]. He apparently bases this theory solely on the need to justify the transmission of the name Heinrich into the family, although this name is certainly not unique to the Burggrafen von Regensburg.
Graf Otto [II] & his wife had five children:
OTTO [III] von Diessen (-28 May 1122, bur Seeon).
HEINRICH (-11 May 1155, bur Regensburg).
LUITPOLD (-19 Feb ----, bur St Stefan).
ADELHEID (-11/12 Jan 1126, bur Kastl).
