AGNES von Rheinfelden (-19 Dec 1111). The Gesta Friderici of Otto of Freising records that "Berhtolfus de castro Zaringen" married "Radolfi filia" but does not name her[226]. The Annales of Berthold record the marriage in 1079 of "Berhtoldus marchio, ducis Berhtoldi filius, adolescens" and "Agnetem, Roudolfi regis filiam"[227]. The Genealogia Zaringorum names "Agnes filia regis Rudolfi Arulacensis" wife of "Berchtoldus", specifying that she was buried with her husband at St Peter in 1111[228]. The necrology of St Peter im Schwarzwald records the death "XIV Kal Jan" of "Agnes uxor ducis Berchtoldi et filia Ruodolfi regis de Arle"[229]. [Betrothed (1077, contract broken) to HERMANN Pfalzgraf von Lotharingen, son of HEINRICH "Furiosus" Pfalzgraf von Lothringen [Ezzonen] & his wife Mathilde of Lotharingia (-20 Sep 1085). The Annales of Berthold name "Herimannus comes Palatinus, qui gener regis Roudolfi futurus erat" in 1077[230]. It is assumed that this passage indicates that Pfalzgraf Hermann was betrothed to one of the daughters of Rudolf von Rheinfelden, although no other reference to this fact has been found. If this is correct, the daughter was presumably Agnes as Adelheid was already married in 1077.] m ([1077/79]) BERTHOLD, son of BERTHOLD I [von Zähringen] Duke of Carinthia & his first wife Richwara of Swabia [Babenberg] ([1050]-12 Apr 1111, bur St Peter in Schwarzwald). He was installed as BERTHOLD II Duke of Swabia in 1092 by Emperor Heinrich IV. He renounced his claims to Swabia in favour of Friedrich I von Staufen, although he retained the title of Duke[231].
