Kind(er):
FRIEDRICH von Goseck, son of --- (-[1042]). Pfalzgraf von Sachsen 1040. Graf im Hassegau.
m AGNES von Weimar, daughter of WILHELM [II] "der Große" Graf von Weimar & his wife ---. The Chronicon Gozecense hints at the correct origin of Agnes, wife of Friedrich von Goseck, when it names "Oudam" as daughter of "comes Fridericus [et] Agnam…de Wimare"[55]. However, according to the Annalista Saxo, the wife of "Fridericus comes" (=Friedrich I Graf von Goseck, Pfalzgraf von Sachsen, from the context) was "filiam Dedonis marchionis, sororem iunioris Dedonis et ex matre Ottonis marchionis de Orlagemunde"[56]. The Genealogica Wettinensis names "Adelhidis…[et] Agnes" as the two daughters of "secundus filius [comitis Tiderici] Dedo" & his wife Oda, naming "Friderico comiti" as wife of Agnes and "Adelbertum archiepiscopum, Dedonem et Fridericum palatinos comites, et filiam nomine Odam quam Adelbertus quidam nobilis cognominatus Seveke de Sumerschenburc accepit uxorem" as their children[57], presumably based on the same source. This Wettin origin is impossible chronologically as the children of Markgraf Dedo must have been born after 1039, the earliest date of his marriage, while Friedrich von Goseck died in [1042].
Pfalzgraf Friedrich & his wife had four children:
ADALBERT von Goseck (-Pfalz zu Goslar 16 Mar 1072, bur Bremen Cathedral).
DEDO von Goseck (-killed in battle Pöhlde 5 May 1056, bur Goslar
FRIEDRICH [II] von Goseck (-Barby 27 May 1088, bur Goseck)
OUDA [Hilaria] von Goseck (-near Zorbau 1088, bur Goseck).
