ALVERADIS, daughter of --- (-after 7 Apr 1210). Her marriage is confirmed by the charter dated 7 Apr 1210 under which [her son] “Adolphus...comes de Altena” confirmed a donation to Kloster Cappenberg made by “Adelheidis ixor Wirici defuncti ministerialis noster”, for the soul of “patris nostri Friderici comitis de Altena, qui ibidem sepultus...”, noting that “ego et mater mea Alveradis et uxor mea Luthgardis” placed “domum in Langeren” on the altar[50]. Europäische Stammtafeln shows “Alveradis (v Krieckenbeck-Millendonk) 1193/1220 T v (Reiner)” as the wife of Graf Friedrich [I][51]. The primary source which suggests her possible parentage has not been identified. Another possibility is that Alveradis was the heiress of Rabodo von der Mark (see Chapter 12) and passed the castle to her son Adolf.
